C program to print an integer

PROGRAM:

#include <stdio.h>

int main()

{

    int num;

    printf("Enter an integer: "); 

    scanf("%d", &num); 

   

    printf("Entered integer is: %d", num);

    return 0;

}

OUTPUT:

Enter a integer: 10

Entered integer is: 10

C program to swap two numbers

PROGRAM-1:

#include <stdio.h>

int main()

{

      double firstNumber, secondNumber, temporaryVariable;

      printf("Enter first number: ");

      scanf("%lf", &firstNumber);

      printf("Enter second number: ");

      scanf("%lf",&secondNumber);

      

      temporaryVariable = firstNumber;

      firstNumber = secondNumber;

      secondNumber = temporaryVariable;

      printf("\nAfter swapping, firstNumber = %.2lf\n", firstNumber);

      printf("After swapping, secondNumber = %.2lf", secondNumber);

      return 0;

}

OUTPUT:

Enter first number: 1.20

Enter second number: 2.45

After swapping, firstNumber = 2.45

After swapping, secondNumber = 1.20

PROGRAM-2:

#include <stdio.h>

int main()

{

    double firstNumber, secondNumber;

    printf("Enter first number: ");

    scanf("%lf", &firstNumber);

    printf("Enter second number: ");

    scanf("%lf",&secondNumber);

  

    firstNumber = firstNumber - secondNumber;

    secondNumber = firstNumber + secondNumber;

    firstNumber = secondNumber - firstNumber;

    printf("\nAfter swapping, firstNumber = %.2lf\n", firstNumber);

    printf("After swapping, secondNumber = %.2lf", secondNumber);

    return 0;

}

OUTPUT:

Enter first number: 10.25

Enter second number: -12.5

After swapping, firstNumber = -12.50

After swapping, secondNumber = 10.25

C program to demonstrate the working of keyword long

PROGRAM:

#include <stdio.h>

int main()

{

    int a;

    long b;

    long long c;

    double e;

    long double f;

    printf("Size of int = %ld bytes \n", sizeof(a));

    printf("Size of long = %ld bytes\n", sizeof(b));

    printf("Size of long long = %ld bytes\n", sizeof(c));

    printf("Size of double = %ld bytes\n", sizeof(e));

    printf("Size of long double = %ld bytes\n", sizeof(f));

    return 0;

}

OUTPUT:

Size of int = 4 bytes

Size of long = 8 bytes

Size of long long = 8 bytes

Size of double = 8 bytes

Size of long double = 16 bytes
