# Multiply a number by 10 using bitwise operator

Here given code implementation process.

```
// C Program
// Multiply a number by 10 using bitwise operator
#include <stdio.h>
void multiplyBy10(int num)
{
// Addition of
// Shift the number to the left by 3
// Shift the number to the left by 1
int result = ((num) << 3) + ((num) << 1);
// Display calculated result
printf(" (%d x 10) %d\n", num, result);
}
int main()
{
// Test
multiplyBy10(6);
multiplyBy10(10);
multiplyBy10(7);
multiplyBy10(-3);
return 0;
}
```

#### Output

```
(6 x 10) 60
(10 x 10) 100
(7 x 10) 70
(-3 x 10) -30
```
