Write an interactive C program which illustrates the following concepts:

(i) Function with no arguments and no return value.

(ii) Function with arguments and no return value.

(iii) Function with arguments and with return value.

 

Write an interactive C program which illustrates the following concepts:

(i) Function with no arguments and no return value.

code:-

#include<stdio.h>
void main()
{
void factorial(int);
int NUM;
clrscr();
printf(“ENTER NUMBER : “);
scanf(“%d”,&NUM);
factorial(NUM);
getch();
}
void factorial(int N)
{
int I,FACT=1;
printf(“ENTER NUMBER : “);
scanf(“%d”,&N);
for(I=N;I>0;I–)
FACT=FACT*I;
printf(“\nFACTORIAL OF GIVEN NUMBER IS %d “,FACT);
}

(ii) Function with arguments and no return value.

code:-

#include<stdio.h>
void main()
{
void factorial(int);
int NUM;
clrscr();
printf(“ENTER NUMBER : “);
scanf(“%d”,&NUM);
factorial(NUM);
getch();
}
void factorial(int N)
{
int I,FACT=1;
for(I=N;I>0;I–)
FACT=FACT*I;
printf(“\nFACTORIAL OF GIVEN NUMBER IS %d “,FACT);
}

(iii) Function with arguments and with return value. 

code:-

#include<stdio.h>
void main()
{
int factorial();
int FACT,NUM;
clrscr();
printf(“ENTER NUMBER : “);
scanf(“%d”,&NUM);
FACT=factorial(NUM);
printf(“\nFACTORIAL OF GIVEN NUMBER IS %d “,FACT);
getch();
}
int factorial(int N)
{
int RESULT=1,I;
for(I=N;I>0;I–)
RESULT=RESULT*I;
return(RESULT);
}
