well... you just passing a 2D array as a 1D array. then just use this code
int findMin(int* array, int num_rows, int num_cols){
int min = *array; // or can use array[0]
int i;
for( i = 1; i < num_rows * num_cols; i++){
if(min > *(array + i))
min = *(array + i);
}
return min;
}
well.. i could not understand the need of copystring function in your program. you are using two pointer to char type of variables. when we deal with pointers then this could be done by = operator..
Well as Narue suggested.. scanf function leaves '\n' into buffer, so when it reaches
while((character=getchar())!= '\n')
reads '\n' from buffer and loop terminates. after this you are using
puts(sentence);
it will print some garbage value on screen bcoz your string is not terminated by a '\0' char. to overcome these problems after using scanf function you need to flush input stream and after also terminate your string with '\0'. Try this:
//Character Manipulation
#include <stdio.h>
void jsw_flush(FILE *in) // Function copied from older post of Narue
{
int ch;
do
ch = getc(in);
while (ch != '\n' && ch != EOF);
clearerr(in);
}
int main()
{
int x;
//for loops
int counter=0;
//for input
char character;
char sentence[20];
printf("Press 1 to use getchar \n Press 2 to use gets \n Press 3 to use sscan \n ");
scanf("%d",&x);
jsw_flush(stdin); // flush input buffer
switch(x)
{
case 1:
printf("Enter something\n");
while((character=getchar())!= '\n')
{
sentence[counter++]=character;
}
sentence[counter] = '\0';
puts(sentence);
break;
}
}
First thing if you are implementing a function then you need to declare that Function like
short int ** getdat (short int ** ,int );
now main() function use it like
int main()
you are using pointer to a pointer variable m but no declaration also m contains nothing.. it's suppose to store a address of a pointer.. first declare it
int **m;
getdet() function is returning pointer to a pointer type of value and you are directing it to a short int n.. also the way to passing address of m is wrong. there are few more mistakes in your program. i suggest first you learn passing pointer to a variable.. and describe your program briefly...
that means it'll store 6 single char including '\0' char. you want to store 6 string having 3 char that means you need to declare a string array or can say 2 dimension char array. your program should be like below assuming string length 4 (including '\0') according to your output:
line 5: when you are asking to the user for the value of n then no need to initialize n=9. line 13: could'nt unserstand the need of /0 here even its \0.. no need for it. line 16: Its '\n' not '/n'. Line 19: place
I am using CODEBLOCKS and I am creating a program that performs basic operations like add, delete and insert on Doubly LinkList , My Program is working fine on older Turboc compilers. But when i run it on codeblock its causing problem when i try to delete a node.
The vast majority of functions will give you some indication of success or failure. Especially with input it's best to make sure that the call succeeded before proceeding as if it did. In the case of scanf, a successful call will return the number of items converted:
Post your code that you have tried and not working.. and please start new thread for new problem.. after your problem get solved mark your thread as solved..
I am actually trying to perform all Arithmatic operations on Large Integer. First i am trying to add two numbers, later i will try to multiply and other operations. that's why i am using polynominals..
I tried to simplyfy my code here is my structure
typedef struct LargeInt
{
int *coeff;
int max_expo_degree; // it will be one less than the size of Largeint
}LargeInt;
My main
int main(void)
{
char num1[79], num2[79], num3[80];
int i;
LargeInt first, second, third;
// Scaning two large values
printf("\n\n Program Large Integer Arithmatics :- ADDITION");
printf("\n\n Enter 1st Number:");
fscanf( stdin ,"%s", num1 );
printf("\n\n Enter 2nd Number:");
fscanf( stdin ,"%s", num2 );
init(&first , num1); // Initializing first LargeInt
init(&second , num2); // Initializing second
add(first , second , &third); // adding first and second
// converting third LargeInt into String
for( i = 0 ; i <= third.max_expo_degree ; i++ )
num3[third.max_expo_degree - i]= third.coeff[i] + '0';
num3[i] = '\0';
printf("\n Addition of \n %s \n %s \n = %s \n", num1 , num2 , num3);
return 0;
}
Initialisation Function
void init(LargeInt *li, char *num)
{
int i , j , len;
len= strlen(num);
// Allocationg Memory space Equal to length of num string
li->coeff = (int *) malloc((len) * sizeof(int));
for (i=len-1,j=0; i>=0; i--,j++)
li->coeff[j] = num[i] - '0';
li->max_expo_degree = len-1; // one less than size
}
The Program is Addition of Large Integers.. Although This program is working But I want to know where i went wrong or what should i need to do to make it better..
# include <stdio.h>
# include <stdlib.h>
# include <ctype.h>
# include <string.h>
typedef struct poly
{
int *coeff;
int degree;
}poly;
void init(poly *, char *);
void add (poly ,poly ,poly *);
int main(void)
{
char num1[80],num2[80],*sum;
int i;
poly p1,p2,p3;
printf("\n\n Program Large Integer Arithmatics :- ADDITION");
printf("\n\n Enter 1st Number:");
fscanf(stdin,"%s",num1);
printf("\n\n Enter 2nd Number:");
fscanf(stdin,"%s",num2);
init(&p1,num1);
init(&p2,num2);
add(p1,p2,&p3);
for(i = 0 ;i <= p3.degree ; i++)
sum[i] = p3.coeff[i] + 48;
sum[i] = '\0';
printf("\n\t Addition = %s",strrev(sum));
free(p1.coeff);
free(p2.coeff);
free(p3.coeff);
return 0;
}
void init(poly *p, char *num)
{
int i,len,j;
len = strlen(num);
p->coeff = (int *) malloc( len * sizeof(int));
//printf("\n %d",len);
for ( i = len - 1 ,j = 0 ; i >= 0 ; i-- , j++)
p->coeff[j] = num[i] - 48;
p->degree = j - 1;
}
void add(poly p1 , poly p2 , poly *p3)
{
int i , l , carry = 0 , s;
l = p1.degree > p2.degree ? p1.degree : p2.degree;
p3->coeff = (int *) malloc ((l+1) * sizeof(int));
for(i = 0 ; i <= l ;i++)
{
if(i > p1.degree)
s = p2.coeff[i] + carry;
else if (i > p2.degree)
s = p1.coeff[i] + carry;
else
s = p1.coeff[i] + p2.coeff[i] + carry;
carry = 0;
carry = s / 10; …
Why do'nt you use Array instead of using five variables. like int num[5]; Declare.. int max, min Use a loop and scan all values initialise max and min variable to num[0] now run a loop and compare all values of array num[5] with both variables..
For that you need a good knowledge of programming, like you need to know worst case complexity, best case complexity and Average time complexity. Read This
# include <stdio.h>
# define MAX 100
int main(void)
{
int oddcount, evencount;
int array[MAX],i,n;
printf("\n Enter Array Size (Between 1 to %d ): ",MAX);
scanf("%d", &n); // User enters Array Size
for(i = 0; i < n; i++)
{
printf("\n Enter %d value: ",i+1);
scanf("%d", &array[i]); // Allows user to enter values into the Array
}
putchar('\n');
printf("\nArray Values: ");
for(i = 0; i < n; i++)
{
printf("\n [%d] value is %3d ", i+1, array[i]); //Prints out the array -- this is where program stops it should carry on down
}
//**************************************//
oddcount = 0;
evencount = 0;
for (i = 0; i < n; i++) // Code determines wheter odd or even.
{
if (array[i] % 2 != 0)
{
//printf("\nThe number %d Is Odd.\n", i);
oddcount ++;
}
else
{
//printf("\nThe number %d Is Even.\n",i);
evencount ++;
}
}
printf("\n Odd Num: %d \n Even Num: %d", oddcount , evencount );
return 0;
}
If you are still getting some problem then post your problem here..
# include <stdio.h>
# define MAX 100
int main(void)
{
int array[MAX],i,n;
printf("\n Enter Array size (1 - %d):",MAX);
scanf("%d", &n);
for(i = 0; i < n; i++)
{
printf("\n Enter %d value :",i+1);
scanf("%d", &array[i]);
}
// whatever else you want to do.......
return 1;
}
main function returns a integer vaule.. that is why return 1 is used.
# define MAX 100
int main(void)
{
int array[MAX],n;
// scan array size from user but it must not be greater than MAX
scanf("%d",&n);
// now run your loop from 0 to less than n and scan array values
return 1;
}
Exactly what you want to do... if you just want to print * then it could be done by using a loop. scan a value from the user and run your loop like this..
int i,num;
// input a value here from user in num..
for(i=1;i<=num;i++)
putchar('*');
