Program 3: Show addition, Subtraction, Multiplication, Division and Remainder of any two numbers
#include<stdio.h> #include<conio.h> void main() { clrscr(); int a=6; int b=5; int c,d,e,f; c=a+b; d=a-b; e=a*b; f=a/b; g=a%b; printf("addition=%d",c); printf("\nsubtraction=%d",d); printf("\nmultiplication=%d",e); printf("\ndivision=%d",f); printf("\nremainder=%d",g); getch(); } Output addition=11 subtraction=1 multiplication=30 division=1 remainder=1 Explanation Here two numbers are assigned in varriable a and b and other varriables c,d,e,f and g are declared for storing the results of addition, subtraction, multiplication, division and remainder respectively. "%" is used to find remainder. "%d" is a specifier of integer. Here "\n" is a specifier that is used to print the text in new line. Exercise: Find out simple interest where principal is 2000, time is 3 years and rate is 2% using a C program.
