#### Program or Solution

```
```
#include<stdio.h>
#include<math.h>
int main()
{
int x1,x2,y1,y2;
int x,y; //temporary variables
float distance;
printf("Enter X and Y coordinates of first point");
scanf("%d %d",&x1,&y1);
printf("Enter X and Y coordinates of Second point");
scanf("%d %d",&x2,&y2);
x=x2-x1;
y=y2-y1;
distance=sqrt((x*x)+(y*y));
printf("Distance: %.2f",distance);
return 0;
}

#### Program Explanation

Get x1,y1,x2 and y2 coordinates of two points(using scanf statement)

Calculate distance by the eculdian distance formula.

Math.sqrt is function available in c library (in math.h header file)to find square root.

Print distance (using printf statement).
