Strings

Q1: What will be the output of the program ? 
#include<stdio.h>

int main()
{
    char p[] = "%d\n";
    p[1] = 'c';
    printf(p, 65);
    return 0;
}

A A

B a

C c

D 65

ANS:A - A

Step 1: char p[] = "%d\n"; The variable p is declared as an array of characters and initialized with string "%d". Step 2: p[1] = 'c'; Here, we overwrite the second element of array p by 'c'. So array p becomes "%c". Step 3: printf(p, 65); becomes printf("%c", 65); Therefore it prints the ASCII value of 65. The output is 'A'.
