what am I coding wrong with a menu?
#include <iostream>
#include <stdio.h>
using namespace std;
int main(int argc, char *argv[])
{
cout << "Hello Welcome to trig 101!" << endl;
cout << "Please select of the following :" << endl;
cout << "1. AsinWt " << endl;
cout << "2. BcosWt " << endl;
cout << "3. CtanWt " << endl;
int getchar(1,2,3,4); int getchar (5,6,7,8);
if char(1){
float a,b,c,d; float e,f,g;
cout << " Please enter Angel A: " << endl; cin >> a;
cout << " Please enter Adjacent Angel a : " << endl; cin >> b;
cout << "Please enter Hypotenuse : " << endl; cin >> c;
cout << " Please enter Time in Military seconds :" << endl; cin >> d;
e = (1/d); f = (b/c); g = a*(f*d)*e;
cout << " your answer is :" << g;
};
else {};
if char(2){
float a,b,c,d; float e,f,g;
cout << " Please enter Angel B: " << endl; cin >> a;
cout << " Please enter Opposite Angel a : " << endl; cin >> b;
cout << "Please enter Hypotenuse : " << endl; cin >> c;
cout << " Please enter Time in Military seconds :" << endl; cin >> d;
e = (1/d); f = (b/c); g = a*(f*d)*e;
cout << " your answer is :" << g;
};
else {};
if char (3){
float a,b,c,d; float e,f,g;
cout << " Please enter Angel C: " << endl; cin >> a;
cout << " Please enter Adjacent Angel a : " << endl; cin >> b;
cout << "Please enter Opposite Angel c : " << endl; cin >> c;
cout << " Please enter Time in Military seconds :" << endl; cin >> d;

return 0;
