Part of my code was skipped as part of my if statment - c++

Question

So im trying to make a calculator and i added a part so i can calculate area, first i asked for integer or geometry math, when i choose geometry, it skips my question of you want to calculate volume. But there were no compiler errors. It everything after " else if (choice == "geometry") {" and until the last line. Anyone knows how to fix.
#include <iostream>
#include <string>
#include <cmath>
using namespace std;
int main()
{
string choice;
cout << "choose integer or geometry\n";
cin >> choice;
if (choice == "integer") {
double num1{ 0 };
double num2{ 0 };
cout << "pick a number\n";
cin >> num1;
cout << "pick another number\n";
cin >> num2;
string integerChoice;
cout << "choose addition, subtraction, multipliction, or division\n";
cin >> integerChoice;
if (integerChoice == "addition") {
cout << num1 << " + " << num2 << " is " << num1 + num2
<< '\n';
}
else if (integerChoice == "subtraction") {
cout << num1 << " - " << num2 << " is " << num1 - num2
<< '\n';
}
else if (integerChoice == "multiplication") {
cout << num1 << " * " << num2 << " is " << num1 * num2
<< '\n';
}
else if (integerChoice == "division") {
cout << num1 << " / " << num2 << " is " << num1 / num2
<< '\n';
}//integer is done
}
else if (choice == "geometry") {
string geoChoice1;
cout << "do you want to calculate volume, enter yes or no\n";
cin >> geoChoice1;
if (geoChoice1 == "yes") {
cout << "choose retangular prism(incudes cubes), cone, or cylinder\n";
string volumeChoice;
cin >> volumeChoice;
if (volumeChoice == "rectangular prism") {
double recPrismLength{ 0 };
double recPrismWidth{ 0 };
double recPrismHeight{ 0 };
cout << "Enter the length\n";
cin >> recPrismLength;
cout << "Enter the width\n";
cin >> recPrismWidth;
cout << "Enter the height\n";
cin >> recPrismHeight;
cout << recPrismLength << " * " << recPrismWidth << " * " << recPrismHeight << " is " <<
recPrismLength * recPrismWidth * recPrismHeight << '\n';
}
else if (volumeChoice == "cylinder") {
float cHeight;
float cRadius;
const double pi{ 3.14159265358979323846 };
float cFormula{ pi * pow(2.0, cRadius) * cHeight };
cout << "Enter the height of the cylinder\n";
cin >> cHeight;
cout << "Enter the radius of the cylinder\n";
cin >> cRadius;
cout << cFormula;
}
else if (geoChoice1 == "no") {

} //this was missing
} //this was missing
Your code did not take into account if the user inputted "Yes" with a capital Y. The code would just conclude that "Yes" would not be equal to "yes". I made a function which converts your input into a lowercase form, then evaluates it, and if it is not "yes" or "no" asks the user to put it again.
There are some other errors which I have put comments on, that you will have to fix.
