A Short Trick For Calculate Area in C

CALCULATE AREA IN C:-

Here is short method to calculate the area of triangle,rectangle and other more as the following 

programming steps.

1.WAP TO CALCULATE THE ARE OF CIRCLE.

#include<stdio.h>

#include<conio.h>

void main()

{

int b,h,r;

float circle_area;

clrscr();

printf("\t\t\tFOR FIND CIRCLE AREA\n\n");

printf("\t\tenter the radius=");

scanf("%d",&r);

circle_area=3.14*r*r;

printf("\n\t\tcircle_area\t=%f\n\n",circle_area);

getch();

}

O/P:-FOR FIND CIRCLE AREA

enter the radius= 2 

circle_area= 12.56

2.WAP TO CALCULATE THE AREA OF TRIANGLE.

#include<stdio.h>

#include<conio.h>

void main()

{

int b,h;

float triangle_area;

clrscr();

printf("\n\t\t\tFOR FIND AREA OF TRIANGLE\n");

printf("\n\t\tenter the hight h=");

scanf("%d",&h);

printf("\n\t\tenter the base b=");

scanf("%d",&b);

triangle_area=0.5*b*h;

printf("\n\t\ttriangle_area\t=%f",triangle_area);

getch();

}

O/P:-FOR FIND AREA OF TRIANGLE

  

     enter the hight h= 2

     enter the base b= 4

     triangle_area=  4.0

3.WAP TO CALCULATE AREA  OF RECTANGLE.

#include<stdio.h>

void main()

{

int b,h,area;

clrscr();

printf("\t\tArea of rectangle");

printf("\tenter the hight");

scanf("%d",&b);

printf("\tenter the value of width=");

scanf("%d",&h);

area=b*h;

printf("Area is=%d",area);

getch();

}

O/P:-Area of rectangle

     

     enter the hight= 2

     enter the value of width= 4

     Area is= 8
