Write a program to check weather a number is positive or not positive using IF



Q1 Write a program to check weather a number  is positive or not positive using if

IF ----If  statement is one of the simplest  decision making control statement.


Syntax

If (expression)
{
        Frist   Statement ;
       …… ………… ……… …………..
       …… ………… …………  ………
      Last  statement;
  }


How to work if statement

The if statement evaluates the take a look at expression within the parenthesis ().
If test condition  is evaluated to true, statements within the body of if are executed.
If test condition  is evaluated to false, statements within the body of if don't  executed

If condition  is true
Int check =10;
If (check < 33)
{
  //  executed code
}
// executed code after if

If condition  is false
Int check =10;
If (check >33)
{
  //  executed code
}

// executed code after if

PROGRAM


#include <stdio.h>
#include <stdlib.h>
int main(int argc, char** argv)
{
    int a;
    printf("ENTER A NUMBER");
    scanf("%d",&a);
    if (a>0)
    {
        printf("positive number");
       
    }
    if(a<=0)
    {
        printf("non positive number");
       
    }
     
    return (EXIT_SUCCESS);
}

OUTPUT

Q1 Write a c program to check a voting AGE condition Given age of someone and that we ought to check whether person is eligible for voting or not. To check that someone is eligible for voting or not, we'd like to examine whether or not person’s age is bigger than or up to eighteen. For this we tend to are reading age in a very variable a and checking the condition a>=18, if the condition is true, "person are eligible for voting" else no. #include <stdio.h> #include <stdlib.h> int main(int argc, char** argv) {         int a;     printf("ENTER A AGE\n");     scanf("%d",&a);     if (a>=18)     {         printf("YOU CAN VOTE");             }     else     {         printf("YOU CAN'T VOTE...
