#include<stdio.h>
#include<string.h>

int main()
{
    char str1[] = "Learn through AptitudeCrack\0.com",  str2[120];
    char *p;
    p = (char*) memccpy(str2, str1, 'i', strlen(str1));
    *p = '\0';
    printf("%s", str2);
    return 0;
}

A Error: in memccpy statement

B Error: invalid pointer conversion

Declaration:
void *memccpy(void *dest, const void *src, int c, size_t n); : Copies a block of n bytes from src to dest With memccpy(), the copying stops as soon as either of the following occurs:
=> the character 'i' is first copied into str2
=> n bytes have been copied into str2
