# C Exercises: Find the largest of three numbers

## C Conditional Statement: Exercise-8 with Solution

Write a C program to find the largest of three numbers.

Pictorial Presentation: Sample Solution:

C Code:

``````#include <stdio.h>
void main()
{
int num1, num2, num3;

printf("Input the values of three numbers : ");
scanf("%d %d %d", &num1, &num2, &num3);
printf("1st Number = %d,\t2nd Number = %d,\t3rd Number = %d\n", num1, num2, num3);
if (num1 > num2)
{
if (num1 > num3)
{
printf("The 1st Number is the greatest among three. \n");
}
else
{
printf("The 3rd Number is the greatest among three. \n");
}
}
else if (num2 > num3)
printf("The 2nd Number is the greatest among three \n");
else
printf("The 3rd Number is the greatest among three \n");
}
```
```

OR

``````#include <stdio.h>
void main() {
int num1, num2, num3;

printf("Input the values of three numbers : ");
scanf("%d %d %d", &num1, &num2, &num3);
printf("1st Number = %d,\t2nd Number = %d,\t3rd Number = %d\n", num1, num2, num3);

if ((num1 > num2) && (num1 > num3))
printf("The 1st Number is the greatest among three. \n");

if ((num2 > num3) && (num2 > num1))
printf("The 2nd Number is the greatest among three \n");

if ((num3 > num1) && (num3 > num2))
printf("The 3rd Number is the greatest among three. \n");

}
```
```

OR

``````#include <stdio.h>
void main() {
int num1, num2, num3,ctr;

printf("Input the values of three numbers : ");
scanf("%d %d %d", &num1, &num2, &num3);
printf("1st Number = %d,\t2nd Number = %d,\t3rd Number = %d\n", num1, num2, num3);

if (num1 > num2 && num1 > num3) ctr=num1;

if (num2 > num3 && num2 > num1) ctr=num2;

if (num3 > num1 && num3 > num2) ctr=num3;
printf("The %d is the greatest among three. \n",ctr);

}
```
```

Sample Output:

```Input the values of three numbers : 12 25 52
1st Number = 12,        2nd Number = 25,        3rd Number = 52
The 3rd Number is the greatest among three
```
