Question

BELOW ARE THREE PROGRAMS CAN YOU MAKE A MENU SO IT ASKS THE USER TO ENTER EITHER 1,2 OR 3 AND THE PROGRAM WILL RUN ACCORDINGLY //PROGRAM 1: #include using namespace std; int main() { int a; int b; int c; cout<<"Hours worked "; cin>>a; cout<<"pay per hour "; cin>>b; if(a<=20){ c=a*b; cout<<"total pay="; cout<>asterick; //This if statement check if the number is valid and prints "*" n times if(asterick < 5 || asterick > 25) { cout<<"Invalid output please try again "< using namespace std; int main(){ int asterick; //for loop will ask for 5 valid inputs and print "*" n times for(int i = 0; i<5; i++) { cout << "Enter number between 5-25 " << endl; //Read input cin >>asterick; //This if statement check if the number is valid and prints "*" n times if(asterick < 5 || asterick > 25) { cout<<"Invalid output please try again "<
