The program is skipping if statement
Hello,
i have a problem with my code which is skipping the if statement (M_choice)
Code:
#include <stdio.h>#include <math.h>
#define PI 3.14159
#define E0 8.85E-12 // This Value is the permittivity of free space
int main(void){
double Er_Air=1.000594, Er_Teflon=2.1, Er_Ceramic=5.6, Er_Glass=7.5, Er_Silicon=11.68;
// Those values representing the relative permittivity of common dielectrics
double Pplates, PlateArea, Distance, Spherical, InnerR, OuterR, Cylindrical, Lingth;
char C_Choice, M_Choice;
printf(" ------ Capacitance Calculator ------ \n");
printf("[P/p]\tParallel Plates\n[C/c]\tCylindrical\n[S/s]\tSpherical");
