Single correct

• A20101020
• B10202010
• C20102010

int fX(char *a){
    char *b = a;
    while(*b)
        b++;
    return b - a;}

One or more correct

• AThe function call fX("abcd") will always return a value
• BAssuming a character array c is declared as char c[] = "abcd" in main(), the function call fX(c) will always return a value
• CThe code of the function will not compile
• DAssuming a character pointer c is declared as char *c = "abcd" in main(), the function call fX(c) will always return a value

#include <stdio.h>
int main() {
    double a[2]={20.0, 25.0}, *p, *q;
    p = a;
    q = p + 1;
    printf("%d,%d", (int)(q - p), (int)(*q - *p));
    return 0;}

Single correct

• A4,8
• B1,5
• C8,5
• D1,8
