Question

USE C Programming LANGUAGE ONLY PLEASE. We use <stdio.h> if that helps. For the following problems, create the prototype function, calling function “int main()”, and function. So the function prototype, function call, and function header/body should be seen in the answer. The processor directive is not needed. Show a sample call from the int main() function for all problems. If you can for the first one please show proof that it has no errors.

1. Write a function called DisplayColumbiaUniversity with no arguments that displays:

*****************

Columbia University

*****************

2. Write a function called DisplayCollegeName that has college name as the argument. Show a sample call that will display Columbia University.

3. Write a function called DisplayArea that displays the area of a room when the width and length are passed as arguments.

4. Write a function called Area that calculates the area of a room and returns area when the width and length are passed as arguments.

5. Write a function called CalculatePerimeter that calculates the perimeter when the width and length are passed as arguments.

Answer 1

Answer: here is the answer for your question:

code:

----------------------------------------------------------------------------------------------------------------------------------------------------------------------

#include <stdio.h>
/*function prototyping is done here */
void DisplayColumbiaUniversity();
void DisplayCollegeName(char college_name[]);
void DisplayArea(int width,int length);
float Area(int width,int length);
float CalculatePerimeter(int width,int length);

int main()
{
char college_name[50];
int width,length,area_of_room;
/*function call is made here in main */
DisplayColumbiaUniversity();
printf("enter college name:");
fgets(college_name,sizeof(college_name),stdin);
DisplayCollegeName(college_name);
printf("enter width :");
scanf("%d",&width);
printf("enter length :");
scanf("%d",&length);
DisplayArea(width,length);
area_of_room=Area(width,length);
CalculatePerimeter(width,length);
}
/*function defination is done here */
void DisplayColumbiaUniversity()
{
char st[]="*****************";
  
char str[]="Columbia University";
  
  
printf("%s \n",st);
printf("%s \n",str);
printf("%s \n",st);
}
void DisplayCollegeName(char college_name[])
{
printf("%s",college_name);
}
void DisplayArea(int width,int length)
{
float area=width*length;
printf("DisplayArea function called and Area of room is %f \n",area);
}
float Area(int width,int length)
{
printf("Area function called and Area returned back to main \n");
float area=width*length;
return area;
}

float CalculatePerimeter(int width,int length)
{
float perimeter=2*length*width;
printf(" perimeter function called and perimeter of the room is %f",perimeter);
}

OUTPUT:

----------------------------------------------------------------------------------------------------------------------------------------------------------------------
