# C program to find sum of two numbers

Write a C program to enter two numbers and find their sum by using the scanf function.

```
Example -
Input: 10
20
Output: Sum of 10 and 20 is: 30
```

## C program to find sum of two numbers

```
#include <stdio.h>
void main()
{
int num1, num2, sum;
printf("Enter first number: ");
scanf("%d", &num1);
printf("Enter second number: ");
scanf("%d", &num2);
sum = num1 + num2;
printf("Sum of %d and %d is: %d", num1, num2, sum);
}
```

**Output**

```
Enter first number: 10
Enter second number: 20
Sum of 10 and 20 is: 30
```

We can also take the input for both of the two numbers together by using just single `scanf`

function.

```
#include <stdio.h>
void main()
{
int num1, num2, sum;
printf("Enter two numbers to find sum\n");
scanf("%d%d", &num1, &num2);
sum = num1 + num2;
printf("Sum of %d and %d is: %d", num1, num2, sum);
}
```

**Output**

```
Enter two numbers to find sum
10
20
Sum of 10 and 20 is: 30
```
