Modify the original code and add an additional function of yourchoice. The function should be unique and something you created forthis assignment. Support your experimentation with screen capturesof executing the new code. Prepare a test table with at least 3distinct test cases listing input and expected output for yourunique function.
#include
void printHelp () {
printf (\"\n\");
printf (\"a: a(x) = xx\n\");
printf (\"b: b(x) = xxx\n\");
printf (\"c: c(x) = x^2 + 2x + 7\n\");
printf (\"q: quit\n\");
}
void a(float x) {
float v = xx;
printf (\" a(%.2f) = %.2f^2 = %.2f\n\", x, x, v);
} // end function a
void b(float x) {
float v = xxx;
printf (\" b(%.2f) = %.2f^3 = %.2f\n\", x, x, v);
} // end function b
void c(float x) {
float v = xx + 2x + 7;
printf (\" c(%.2f) = %.2f^2 + 2%.2f + 7 = %.2f\n\",
x, x, x, v);
} // end function c
int menu () {
char selection;
float x;
printHelp ();
scanf (\"%s\", &selection);
if (selection == 'q') return 1;
scanf (\"%f\", &x);
if (selection == 'a') a(x);
if (selection == 'b') b(x);
if (selection == 'c') c(x);
return 0;
} // end function menu
int main() {
while (menu() == 0);
printf (\"... bye ...\n\");
return 0;
} // end main
