Programming Example
C Program to Calculate Area of Rectangle
In this c program we will calculate Area of Rectangle
#include"stdio.h"
int main() {
int length, breadth, area;
printf("\nEnter the Length of Rectangle : \n");
scanf("%d", &length);
printf("\nEnter the Breadth of Rectangle : \n");
scanf("%d", &breadth);
area = length * breadth;
printf("\nArea of Rectangle : %d \n\n", area);
return (0);
}Enter the Length of Rectangle :
6
Enter the Breadth of Rectangle :
7
Area of Rectangle : 42

First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.
After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
