Okay so I have my program almost completed but, I am stuck on something... I need to include basic math functions such as abs, sqrt, pow, exp, log, sin, cos, tan, asin, acos, atan, sinh, cosh, and tanh.

Do I put these math functions as a case... and if so how do I put it as the result of a function or variable inputed... did that question make sense?

ok lets say...

if one of my cases is

how do I get one of the basic math functions to process one of the prior cases... so in better words i want to say something likeCode:case '+': res=a+b; cout<<res;

sqrt(res)...

except when it gets to pow of course... I will NOT use "res".

heres my code

I hope that made sense... thanks.Code:#include <iostream> #include <cmath> using namespace std; int getOperand(char ch); int IsInList(char ch); char cVar[10]; double dVar[10]; int varNum; int main ( ) { char ch; char op; int op1; int op2; double res; varNum = 0; cout<<"You will be inputing numbers associated with variables.\n"; cout<<"For Example a=3, b=2, etc. Once the values are inputed\n"; cout<<"you are able to input a specific math function, such as\n"; cout<<"a+b, a*b, etc. Please input a value below:\n"; cout<<"\n"; cout<<"\n"; do { cout << ">> "; cin >> ch; if (ch == 'q') { break; } op1 = getOperand(ch); cin >> ch; if(ch == '=') { cin >> dVar[op1]; cout << cVar[op1] << " =\n\n"; cout << " " << dVar[op1] << "\n\n"; } else { op = ch; cin >> ch; op2 = getOperand(ch); switch(op) { case '+': res = dVar[op1] + dVar[op2]; cout << "Ans = \n\n"; cout << " " << res << "\n\n"; break; case '*': res = dVar[op1] * dVar[op2]; cout << "Ans = \n\n"; cout << " " << res << "\n\n"; break; case '/': res = dVar[op1]/dVar[op2]; cout << "Ans = \n\n"; cout << " " << res << "\n\n"; break; case '-': res = dVar[op1] - dVar[op2]; cout << "Ans = \n\n"; cout << " " << res << "\n\n"; break; case '%': res = fmod(dVar[op1], dVar[op2]); cout << "Ans = \n\n"; cout << " " << res << "\n\n"; break; } } } while (1); } int getOperand(char ch) { int iVar; iVar = IsInList(ch); if (iVar == -1) { cVar[varNum] = ch; iVar = varNum; varNum++; } return iVar; } int IsInList(char ch) { for (int i = 0; i < 10; i++) { if(ch == cVar[i]) { return i; } } return -1; }
