Sol:

#include <stdio.h>
 int main()
 {
     int age;
     char name[20];
     printf("Enter name ");
     scanf("%s",name);
     printf("Enter age ");
     scanf("%d",&age);
     if(age>=18)
         printf("you can vote");
     else
         printf("you cannot vote");
 return 0;
 }

Output:

case 1:
Enter name amit
Enter age 12
you cannot vote
case 2:

Question: 12

Write a C program to take input for a number if number<=10 calculate and print its square?

Sol:

#include <stdio.h>
 int main()
 {
     int a,b;
     printf("Enter any no ");
     scanf("%d",&a);
     if(a<=10)
         {
             b=a*a;
             printf("square = %d",b);
         }
 return 0;
 }

Output:

case :1
Enter any no 5
square = 25
case 2:
Enter any no 12
(no ouput as condition is false)

Question: 13

Write a C program to take input for a number if number<=10 calculate and print its cube otherwise print its square?

Sol:

#include <stdio.h>
 int main()
 {
     int a,b;
     printf("Enter any no ");
     scanf("%d",&a);
     if(a<=10)
         {
             b=a*a*a;
             printf("cube = %d",b);
         }
         else
         {
             b=a*a;
             printf("square = %d",b);
         }
     return(0);
 }

Output:

case :1
Enter any no 5
cube = 125
case 2:
Enter any no 12
square = 144

Question: 14

Write a C program to take a number check and print whether the number is +ve , -ve or zero?

Sol:

#include <stdio.h>
 int main()
 {
     int a;
     printf("Enter any no ");
     scanf("%d",&a);
     if(a==0)
         printf("value is zero");
     else
         if(a>0)
             printf("value is +ve");
         else
             printf("value is -ve");
     return 0;
 }

Output:

case 1:
Enter any no 25
value is +ve
case 2:
Enter any no -96
value is -ve
case 3:
Enter any no 0
value is zero

Question: 15

Write a C program to take a number check and print whether the number is even , odd or zero?

Sol:

#include <stdio.h>
 int main()
 {
     int a;
     printf("Enter any no ");
     scanf("%d",&a);
     if(a==0)
         printf("value is zero");
     else
         if(a%2==0)
             printf("value is even");
         else
             printf("value is odd");
 return 0;
 }

Output:

case 1:
Enter any no 25
value is odd
case 2:
Enter any no 36
value is even
case 3:
Enter any no 0
value is zero
