Personal outlook: don't cast the return of malloc, in C (don't use malloc in C++). In any project that isn't trivial, the probability of correctness is greater if one relies on the compiler.

I just made one more try for the followin.

When you have the file as .c in MS compiler for the code

int main(){
int *ptr=malloc(10);
return 0;
}

but it gives when the file name is a .cpp file but with the .c file it does not run into any error for the code when executed. That is could not run into the hidden error.

Try compiling in strict mode. You can even try online compiler .

it could be alot simpler a problem...
try:
char *x = "C-PROGRAMMING";
char *Prog = (char *)malloc(strlen(14));

The online compiler gives error when not type casted.
