# If Condition Programs Set 1

Question: 1

Write a C program to take input for a number, check and print whether the number is +ve or not?

Sol:

```#include <stdio.h>
int main()
{
int a;
printf("Enter any no ");
scanf("%d",&a);
if(a>0)
printf("number is +ve");
else
printf("number is not +ve");
return 0;
}```

### Output:

case 1:

Enter any no 25
number is +ve

Case :2

Enter any no -96
number is not +ve

Question : 2

Write a C program to take input for a number, check and print whether the number is -ve or not?

Sol:

```#include <stdio.h>
int main()
{
int a;
printf("Enter any no ");
scanf("%d",&a);
if(a<0)
printf("number is -ve");
else
printf("number is not -ve");
return 0;
}```

Output:

case 1:
Enter any no 25
number is not -ve
case 2:
Enter any no -96
number is -ve

Question: 3

Write a C program to take input for a number, check and print whether the number is even or not?

Sol:

```#include <stdio.h>
int main()
{
int a;
printf("Enter any no ");
scanf("%d",&a);
if(a%2==0)
printf("number is even");
else
printf("number is not even");
return 0;
}```

## Output:

case 1:
Enter any no 26
number is even
case 2:
Enter any no 95
number is not even

Question: 4

Write a C program to take input for a number, check and print whether the number is odd or not?

Sol:

```#include <stdio.h>
int main()
{
int a;
printf("Enter any no ");
scanf("%d",&a);
if(a%2==1) //if(a%2!=0)
printf("number is odd");
else
printf("number is not odd");
return 0;
}```

## Output:

case 1:
Enter any no 45
number is odd
case 2:
Enter any no 67
number is odd

Question: 5

Write a C program to take input for a number, check and print whether the number is a multiple of 7 or not?

Sol:

```#include <stdio.h>
int main()
{
int a;
printf("Enter any no ");
scanf("%d",&a);
if(a%7==0)
printf("number is multiple of 7");
else
printf("number is not multiple 7");
return 0;
}```

## Output:

case 1:
Enter any no 24
number is not multiple 7
case 2:
Enter any no 77
number is multiple of 7
