I'm using Dev-C++ 4.9.9.2
Im making my arrays dynamically and I am calling on a function to allocate the memory for me, but I received the warning:
"[Warning] assignment makes pointer from integer without a cast "
This occurs in main when alocate is called
Main funtion:
int main()
{
int exit,temp,SIZE,i,j,fromA,toB, tryagain=1, counter;
char filename[50];
FILE *infile;
int **matrix; /*point to array of pointers*/
int **tmpmat; /*Holds values for matrix raised to a power*/
int **C;
printf("Enter File Name: ");
scanf("%s",filename);
infile = fopen(filename, "r+"); /*opens data file*/
if(infile == NULL) /*check to see if file opened properly*/
{
printf("Cannot open the input file- Enter 1 to exit: ");
scanf("%d",&exit);
return(-1);
}
fscanf(infile, "%d", &SIZE);/*reads size of adj matrix*/
printf("The adjacency matrix size is %dx%d\n\n", SIZE, SIZE);
/*******Making Array dynamically**************/
matrix = alocate(SIZE);
tmpmat = alocate(SIZE);
C = alocate(SIZE);
/************End of dyanamic array making********/Here's the funtions it calls
I get the Warning: return makes integer from pointer without a cast
int alocate(int SIZE)
{
int i;
int **new;
new = malloc(SIZE * sizeof(int *));
if (new == NULL) {
printf("Error: malloc could not allocate %d bytes for a\n", (SIZE * sizeof(int *)));
return -1;
}
for (i=0; i<SIZE; i++)
new[i] = malloc(SIZE * sizeof(int));
return new;
}
