hi, i'm trying to figure out how to fix this warning:
decode.c(77) : warning C4715: 'get_msg' : not all control paths return a value
i understand that my get_msg could not always return a value, i'm just not sure how to state that in my code? can anyone suggest anything? should i use an if/else statement?
#include <stdio.h>
#define MAX 53
FILE *csis, *fp;
void get_code(char code[]);
int get_msg(int msg[]);
void sort_msg(int msg[],int msg_size);
void decode_msg(char code[], int msg[], int msd_size);
void main(void)
{ //Start
char code[MAX];
int msg[MAX];
int msg_size;
get_code(code);
msg_size = get_msg(msg);
sort_msg(msg, msg_size);
decode_msg(code, msg, msg_size);
}//End main
void get_code(char code[])
{
int i;
fopen_s(&fp, "codefile.txt", "r");
while (!feof(fp)) //loops file till end
fscanf_s(fp, "%c\n", &code); //places file contents in i
for (i = 0; code[i]= *code; i++) //adds i to it self to continue with contents
;}//end get_code
int get_msg(int msg[]){
int j;
fopen_s(&csis, "msgfile.txt", "r");
while (!feof(csis))
fscanf_s(csis, "%c\n", &msg);
for (j = 0; msg[j]= *msg; j++)
return j;
}//end get_msg
void sort_msg(int msg[],int msg_size){
int i, j, temp;
for (i = 1; i < msg_size; i++) {
temp = msg[i];
j = i - 1;
while (j >= 0 && temp < msg[j]) {
msg[j+1] = msg[j];
j = j - 1;
}
msg[j+1] = temp;
}
}//end sort_msg
void decode_msg(char code[], int msg[], int msg_size){
int i;
for(i=0; i< msg_size; i++)
printf("%c", code[msg[i] %10]);
printf("\n");
}//end decode_msg
