C Program to Convert Binary Code of a Number into its Equivalent Gray’s Code without using Recursion.

```
#include <stdio.h>
```
```
#include <math.h>
```
```
 
```
```
int bintogray(int);
```
```
 
```
```
int main ()
```
```
{
```
```
    int bin, gray;
```
```
 
```
```
    printf("Enter a binary number: ");
```
```
    scanf("%d", &bin);
```
```
    gray = bintogray(bin);
```

    printf("The gray code of %d is %d\n", bin, gray);

```
    return 0;
```
```
}
```
```
 
```
```
int bintogray(int bin)
```
```
{
```
```
    int a, b, result = 0, i = 0;
```
```
 
```
```
    while (bin != 0)
```
```
    {
```
```
        a = bin % 10;
```
```
        bin = bin / 10;
```
```
        b = bin % 10;
```
```
        if ((a && !b) || (!a && b))
```
```
        {
```

            result = result + pow(10, i);

```
        }
```
```
        i++;
```
```
    }
```
```
    return result;
