C Program to read two integers 'a' and 'b' and print quotient and remainder when 'a' is divided by 'b' without using the "%' operator or 'mod' function.

Suppose a=39, b=7, if 'a' is divided by 'b' quotient is '5' and remainder is 4;

Consider q=a/b, so 'q' is the quotient.

a=39, b=7, the statement q=a/b evaluates q=5

remainder = a‒q*b = 39‒5*7= 39‒35 = 4

so r=a‒q*b will calculate the remainder.

/* Program to print quotient and remainder without "%' and 'mod' function */

#include <stdio.h>

main()

{

/* Local definition */

int a,b,q,r;

/*statements */

printf("Enter a,b values.....");

scanf("%d %d", &a,&b);

q=a/b;

r=a‒q*b;

printf("Quotient is.....%d", q);

printf("Remainder is.....%d", r);

} /* main */

OUTPUT

Enter a, b values.....39 7

Quotient is.....5

Remainder is.....4

EXPLANATION: In the above program the variables a,b,q,r are declared as integer type. The scanf() function reads values of the two variables ‘a' and 'b'. 'q' is a variable holds the result of a/b and variable 'r' holds the result of (a‒q*b). After computing quotient 'q' and remainder 'r' are printed. Note that in this program the remainder is calculated without modular division.
