Question

create C program that:

1. Has a triangle function (which receives and sends no arguments) to:
   1. Calculates the area of ANY* triangle (prompts the user for necessary values.)
   2. Uses integer values and displays them in a field width of 8.
   3. Provides an answer to the user such as follows:
      • The area of the triangle with base 7 and height 8 is 28.
2. Has a circle function (which receives and sends no arguments) to:
   1. Prompts the user for necessary values.
   2. Accurately calculate the circumference of ANY* circle.
   3. Uses a constant for PI (See textbook for constants)
   4. Displays answer with values left-justified, with field with of 4 and only two decimal values
   5. Displays the answer to the user such as follows:
      • The circumference of the circle with a radius of 6 is 37.7.

Answer 1

the C program is shown below:

#include <stdio.h>
#define pi 3.14// constant declaration
void triangle()
{
int height,base,area_tri;
printf("enter the value of height and base of triangle");
scanf("%d %d",&height,&base);
area_tri=(base*height)/2;
printf("area of the triangle is %d\n",area_tri);
}
void circle()
{
int radious;
double circumference;
printf("enter the value of radious");
scanf("%d",&radious);
circumference=(float)(2*pi*radious);
printf("the circumference of circle with radious %d is %.2f",radious,circumference);// here %.2F gives us precision ipto 2 decimal places
}
int main()
{
triangle();
circle();
}
