How to take different types of input in c++ -

in program i'm working on, scan 1 character input, (w,a,s,d)

cin >> input; 

but want make if user enters 'p', example, further allow him enter 2 more values.

for example, entering 'a' move left. entering 'p 3 100' place number 100 in array position 3.

id prefer dont have press enter after inputting p, because means add condition statement if (input==p)

i recommend keep simple:

just keep checking 1 character and, if given character p ask other arguments user.

for instance:

edit code edited match op requirements.

char option; cout << "enter option: "; cin >> option;  switch (option) {     case 'a':         // things.         break;      case 'p':         int number, position;         cin >> number;         cin >> position;         // things.         break;     // don't forget default case. }
