C Programs Practicals

1.Write a C program print ASCII value of any character

#include <stdio.h>
#include <conio.h>
int main() {  
    char c;
    printf("Enter a character: ");
    scanf("%c", &c);  
    
    // %d displays the integer value of a character
    // %c displays the actual character
    printf("ASCII value of %c = %d", c, c);
    
    return 0;
}

output:

Enter a character: G
ASCII value of G = 71

2.Write a C program using enum keyword.

#include <stdio.h>
#include <conio.h>
enum week {Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday};

int main()
{
   
    enum week today;
    today = Tuesday;
    printf("Day %d",today+1);
    return 0;
}

output:

Day 3

3.Write a C program for typecasting the value from integer to float

#include <stdio.h>
#include <conio.h>
main() {

   int a = 17, b = 5;
   float ans;

   ans = (float) (a + b);
   printf("Value of Ans : %fn", ans );
}

output:

Value of Ans : 22.000000

4.Write a C program to take character from user using getchar() function and print that character using putchar() function.

#include <stdio.h>
#include <conio.h>
int main()
{
   char c;
   printf("Enter some character....n");

      c = getchar();
      printf("n Entered character is: ");
      putchar(c);
      printf("n");
    
   return 0;
}

output:

Enter some character....
A
Entered character is: A

5.Write a program to perform arithmetic operations on two numbers.

#include <stdio.h>
#include <conio.h>
int main()
{
    int num1, num2;
    int sum, sub, mult, mod;
    float div;
    printf("Enter any two numbers: ");
    scanf("%d%d", &num1, &num2);

    sum = num1 + num2;
    sub = num1 - num2;
    mult = num1 * num2;
    div = (float)num1 / num2;
    mod = num1 % num2;
    
    
     printf("Addition = %dn", sum);
    printf("Substraction = %dn", sub);
    printf("Multliplication = %dn", mult);
    printf("Divisoin = %fn", div);
    printf("Modulus = %d", mod);
    
   return 0;
}

output:

Enter any two numbers: 5
10
Addition = 15
Substraction = -5
Multliplication = 50
Divisoin = 0.500000
Modulus = 5

6.Write a program to find maximum number from two numbers using conditional operator(Ternary operator).

#include <stdio.h>
#include <conio.h>
int main()
{
    int num1, num2, max;
    
    printf("Enter two numbers: ");
    scanf("%d%d", &num1, &num2);
    
    max = (num1 > num2) ? num1 : num2;
    
    printf("Maximum between %d and %d is %d", num1, num2, max);

    
    
   return 0;
}

output:

Enter two numbers: 10 15
Maximum between 10 and 15 is 15

7.Write a program to perform Postfix increment and Postfix Decrement using Increment/Decrement Operators.

#include <stdio.h>
#include <conio.h>
int main()
{
    int x = 12, y = 1;

    printf("Initial value of x = %dn", x); 
    printf("Initial value of y = %dnn", y); 

    y = x++; 

    printf("After incrementing by 1: x = %dn", x);
    printf("y = %dnn", y);

    y = x--; 

    printf("After decrementing by 1: x = %dn", x);
    printf("y = %dnn", y);

   
    return 0;
}

output:

Initial value of x = 12
Initial value of y = 1

After incrementing by 1: x = 13
y = 12

After decrementing by 1: x = 12
y = 13
