# C Program to Find Largest of Three Numbers

Howdy readers, today you will learn how to find the largest of three numbers using C Programming language.

This program asks the user to enter three numbers, then it finds the largest of them using if-else statement and comparison operators.

So, without any delay, let’s begin this tutorial.

## C Program to Find Largest of Three Numbers

C Program

```// C Program to Find Largest of Three Numbers
#include <stdio.h>
int main(){
int a, b, c;

printf("Enter the first number: ");
scanf("%d", &a);
printf("Enter the second number: ");
scanf("%d", &b);
printf("Enter the three number: ");
scanf("%d", &c);

// Finding largest number
if (a >= b && a >= c){
printf("%d is the largest number.", a);
}
else if (b >= a && b >= c){
printf("%d is the largest number.", b);
}
else{
printf("%d is the largest number.", c);
}

return 0;
}
```

Output

```Enter the first number: 7
Enter the second number: 12
Enter the three number: 5
12 is the largest number.
```

Explanation

```    int a, b, c;
```

In this program, we have declared three int data type variables named a, b and c.

```    // Asking for input
printf("Enter the first number: ");
scanf("%d", &a);
printf("Enter the second number: ");
scanf("%d", &b);
printf("Enter the three number: ");
scanf("%d", &c);
```

Then, the user is asked to enter three numbers. These numbers get stored in the a, b and c named variables respectively.

```    if (a >= b && a >= c){
printf("%d is the largest number.", a);
}
```

Now, we check whether a is greater than b and c or not. If the condition is True, then a is the largest number and we print it on the screen using printf() function.

```    else if (b >= a && b >= c){
printf("%d is the largest number.", b);
}
```

Similarly, we check whether b is greater than a and c or not. If this statement is True, then b is the largest of the three.

```    else{
printf("%d is the largest number.", c);
}
```

If neither of the above two statements are True, then it clearly means c is the largest number and we print it’s value on the screen using printf() function.

## Conclusion

I hope after reading this post, you understand how to write a program to find the largest of three numbers using C Programming language.
