Tricky Program's In C Programming Language

• Program to Print even odd number without using if-else statement using switch case:

#include<stdio.h>
int main()
{
int no;
printf("enter the no\n");
scanf("%d",&no);
switch(no%2)
{
case 0: printf("no is even");
break;
case 1: printf("no is odd");
}

}

Output:

....................................................................

• Print welcome without using semicolons:

• Using if-statement:

Using C:

#include<stdio.h>
void main()
{
       if(printf("welcome"))
        {}
} 

Using C++:

#include<iostream.h>

void main()

{

       if(cout<<"welcome")
    {}


}

• Using while loop:

#include<stdio.h>
void main()
{
while(!printf("welcome"))
{}
}

• Using switch case:

#include<stdio.h>
void main()
{
switch(printf("welcome"))
{}

}

Output:
