Q1:

What will be the output of the program?

#include<stdio.h>
int main()
{
    int i = 1;
    switch(i)
    {
        printf('Hello\n');
        case 1:
            printf('Hi\n');
            break;
        case 2:
            printf('\nBye\n');
            break;
    }
    return 0;
}

switch(i) has the variable i it has the value '1'(one). Then case 1: statements got executed. so, it prints 'Hi'. The break; statement make the program to be exited from switch-case statement. switch-case do not execute any statements outside these blocks case and default Hence the output is 'Hi'.
