C Program To Compare two variables
Hey Shouters !! Today we will understand C Program to Compare two variables. We can compare two variable to find some relation between them.
Some of the popular Relations are :
- To find the largest number
- To find the smallest number
- Check that the variables are equal or not.
1. C Program to find the largest number-
If you have two variables suppose a=10 and b =20. To find the largest number we have to compare the two variables using the relational operator greater than (>) to get the largest number.

// C Program to find the largest number #include <stdio.h> #include<conio.h> int main() { int a =10; int b =20; // Declaration and definition printf("Comparing the variables \n"); if(a>b) // comparing the variables { printf(" a is the largest numbers%d",a); } else { printf("b is the largest number %d",b); } } |

<strong>Output - </strong> Comparing the variables b is the largest number 20 |
2. C Program to find the smallest number-
If you have two variables suppose a=20 and b =30. To find the smallest number we have to compare the two variables using the relational operator lesser than (<) to get the smallest number.

// C Program to find the smallest number #include <stdio.h> #include<conio.h> int main() { int a =20; int b =30; // Declaration and definition printf("Comparing the variables \n"); if(a<b) // comparing the variables { printf(" a is the smallest numbers %d",a); } else { printf("b is the smallest number %d",b); } } |

Output - Comparing the variables a is the smallest number 20 |
3. C Program to check the variables are equal or not –
In this program, we will see how to check that the two variables are equal or not. We will use the relational operator double equals (==) to compare the variables.
Suppose a and b are two variables and a=25 and b =25. Then the if statement will work. and if a=25 and b =20 then else statement will be executed.

// C Program to check the variables are equal or not #include <stdio.h> #include<conio.h> int main() { int a =25; int b =25; // Declaration and definition printf("Comparing the variables \n"); if(a==b) // comparing the variables { printf(" a is equal to b and both are %d",a); } else { printf("The variables are not equal"); } } |

<strong>Output - </strong> Comparing the variables a is equal to b and both are 25 |
Now you can write a C Program to compare two variables to check other relations as well.
