Write a C program to calculate the distance between the two points.  /* Write a C program to calculate the distance between the two points. */ #include<stdio.h> #include<math.h> int main( ) {     int x1,x2,y1,y2;     int x,y;     float d;     printf("Enter the coordinates of first point(x1,y1):");     scanf("%d%d",&x1,&y1);     printf("Enter the coordinates of the second point(x2,y2):");     scanf("%d%d",&x2,&y2);     x = (x2-x1);     y = (y2-y1);     d = sqrt((x*x)+(y*y));     printf("Distance = %.2f\n",d);     return 0; }    Output: Enter the coordinates of first point(x1,y1):3 7 Enter the coordinates of the second point(x2,y2):5 8 Distance = 2.236
Write a C program that accepts 4 integers p, q, r, s from the user where r and s are positive and p is even. If q is greater than r and s is greater than p and if the sum of r and s is greater than the sum of p and q print "Correct values", otherwise print "Wrong values". Complete Lab Manual Download Below
