How would I create a C Code using a simple mathematical equation. The code NEEDS TO prompt users to enter variables and calculate based on the formula chosen. It also needs to be used in online compilers such as ideone and repl.it

I would like to use the midpoint formula:

An example of a C Code prompt using a different math equation is as follows:

#include #include

int main() { double a, b, c, discriminant, root1, root2, realPart, imagPart; printf("Enter coefficients a, b and c: "); scanf("%lf %lf %lf", &a, &b, &c);

discriminant = b * b - 4 * a *c;

//condition for real and different roots if (discriminant > 0) { root1 = (-b + sqrt(discriminant)) / (2 * a); root2 = (-b - sqrt(discriminant)) / (2 * a); printf("root1 = %.2lf and root2 = %.2lf", root1, root2); }

//condition for real and equal roots else if (discriminant ==0) { root1 = root2 = -b / (2 * a); printf("root1 = .2%lf and root2 = .2lf;", root1); }

// if roots are not real else { realPart = -b / (2 * a); imagPart = sqrt(-discriminant) / (2 * a); printf("root1 = %.2lf+%.21lfi and root2 = %.2f-%.2fi", realPart, imagPart, realPart, imagPart); } return 0; }
