Here are few very simple and basic C language programs with C programming examples that you will use to understand the basics very easily.

Write a C programme to calculate area of a rectangle :

#include<stdio.h>
int main(){

          Int l, b, area;
          printf(“Enter length and breadth of a rectangle \n”);
          scanf(“%d %d”, &l, &b);
          area = l *b;
          printf(“Area of rectangle is %d \n”, area);
          return 0;
}

Write a C program to calculate area of a circle :

#include<stdio.h>
int main(){

          float r, area;
          printf(“Enter the radius of the circle \n”);
          scanf(“%f”, &r);
          area = 3.14*r*r;
          printf(“Area of circle is %f \n”, area);
          return 0;
}

Write a C program to calculate simple intrest (SI) :

#include<stdio.h>
int main(){

          float p, r, t , si;
          printf(“Enter the values of p, r, and t respectively \n”);
          scanf(“%f %f %f”, &p, &r, &t);
          si= p * r * t /100;
          printf(“Simple interest is %f \n”, si);
          return 0;
}
