Programming (Case Study) - CSU

 

  Joio Franz C Gianan #3

Write a program that gives the choice of computing any of the following: the area of a circle, a square, a rectangle, or a triangle. The program should include a loop to allow the user to do as many calculations a desired. Assume the 1 2 3 4 5

following options: Area of circle Area of square Area of rectangle Area of triangle Exit

#include<stdio.h> void main() { int Choice=0; float pi=3.14; float ac=0; float as=0; float ar=0; float at=0; float r=0; float s=0; float l=0; float float w=0; b=0; float h=0; printf("1 printf("2 printf("3 printf("4 printf("5

-

Area of circle\n"); Area of square\n"); Area of rectangle\n"); rectangle\n") ; Area of triangle\n"); Exit\n\n");

printf("Choice:"); scanf("%d", &Choice);
