1.5.7.Use printf to output variable

#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.
