#include <stdio.h> 
    
    int main() 
    {  
        int term;       /* term used in two expressions */ 

        term = 3 * 5;  
        printf("Twice %d is %d\n", term, 2*term);  
        printf("Three times %d is %d\n", term, 3*term);
        return (0);
    }

Twice 15 is 30
Three times 15 is 45

The number of %d conversions should match the number of expressions.
