C Programming Examples with Output Part – 1  ~ Image by ©Ishwaranand

1) Write a program to accept two numbers & swap them.

#include <stdio.h>
#include <conio.h>
void main()
{
         int a, b, temp;
         printf(“Enter two numbers : “);
         scanf(“%d%d”, &a, &b);
         printf(“nOriginal values are a = %d b = %d”, a, b);
          temp = a;
          a = b;
          b = temp;
          printf(“nAfter exchange a = %d b = %d”, a, b);
          getch();
}
Output:
Enter two numbers : 10 20
Original values are a = 10 b = 20
After exchange a = 20 b = 10

2) Write a program to accept two numbers & swap them without an extra (third) variable.

#include <stdio.h>
#include <conio.h>
void main()
{
          int a, b;
          printf(“Enter two numbers : “);
          scanf(“%d%d”, &a, &b);
          printf(“nOriginal values are a = %d b = %d”, a, b);
          a = a + b;
          b = a – b;
          a = a – b;
          printf(“nAfter exchange a = %d b = %d”, a, b);
          getch();
}
Output:
Enter two numbers : 10 20
Original values are a = 10 b = 20
After exchange a = 20 b = 10

3) What is the output of the following program? – 3 Number value equation

 void main()
{
          int intN = 55;
          int intM = 10;
          char X = ‘A’ ;
          intN +=50;
          printf(“1. Updated value of intN ID % FN”, X);
          printf(“2. Updated value of X is % dn”, X);
          X=’B’;
          printf(“3. Updated value of X is % cn”, X);
          intN -=8;
          printf(“4. Updated value of intN is %dn”,intN);
          intN++;
          printf(“5. Updated value of intN is %dn”, intN);
          intN= intN++  + ++ItM;
          printf(“6. Updated value of intN is ;%d intM is;%dn”, intN, intM);
}
Output:
1.Updated value of intN is 105
2.Updated value of X is 65
3.Updated value of X is B
4.Updated value of intN is 97
5.Updated value of intN is 98
6.Updated value of intN is :110 intM is:11
