Write a C program to enter length and breadth of a rectangle and find its perimeter.
 

Static program

#include<stdio.h>
#include<conio.h>
void main()
{
    clrscr();
    int length=10,width=5,per;
    per = 2*(length+width);
    printf("The perimenter of rectangle is :- %d ",per);
getch();
}

 Output :- 

Dynamic Program 

#include<stdio.h>
#include<conio.h>
void main()

{
    clrscr();
    int length,width,per;
    printf("Enter the length and breadth of a rectngle :-");
    scanf("%d %d",&length,&width);
    per = 2*(length+width);
    printf("The perimeter of rectangle is :- %d",per);
getch();
}

 

Output :-
