Program Code
//Write a menu driven program to find out Factorial No, Prime No, Even Odd no #include<stdio.h> #include<conio.h> void fact(); void prime(); void OE(); void main() { int ch,a; clrscr(); printf("1.Factorial\n"); printf("2.Prime or not\n"); printf("3.Odd or even\n"); printf("4.Exit\n"); printf("\nEnter your choice\n"); scanf("%d",&ch); switch(ch) { case 1: fact(); break; case 2: prime(); break; case 3: OE(); break; case 4: printf("exit"); printf("Thank You "); exit(); break; } getch(); } void fact() { int fact=1,i,n=5; for(i=1;i<=n;i++) { fact=fact*i; } printf("Factorial=%d",fact); } void prime() { int p=0,i,n; printf("enter value"); scanf("%d",&n); for(i=2;i<=n/2;i++) { if(n%i==0) { p=1; break; } } if(p==0) printf("Number is prime"); else printf("not prime"); } void OE() { int no; printf("enter value"); scanf("%d",&no); if((no%2)==0) { printf("number even"); } else { printf("number odd"); } }


Input Values(You must enter all user input value here, that you want to use during runtime)



To Run C Program 1. comment #include<conio.h>, clrscr(), getch(). This will not work online. This (1.) will be done automatically..., So don't worry. 2. void main() change to int main() and return 0 This (2.) will do it manually, Otherwise it give runtime error but with correct output..., So don't worry
