Question

Write a C++ function that lets the user enter alphabet letters into a static char array until either the user enters a non-alphabet letter or, it has reached the MAXSIZE. You can use the isalpha([Char]) function to check if the input is an alphabet letter or not.

void fillArray (char ar[], size_t& size){

// this is the function prototype

}

Answer 1

C++ CODE:

#include <iostream>

using namespace std;

#define MAXSIZE 10

void fillArray (char ar[], size_t& size){
    char ch;
    cout << "Enter letters: ";
    ch = cin.get();//Read a character from input stream
    while(size < MAXSIZE && isalpha(ch)){//Check if character is alphabet or not
        ar[size] = ch;
        size++;
        ch = cin.get();
    }
}

int main(){
    char ar[MAXSIZE];
    size_t size = 0;
    fillArray(ar, size);
    cout << "Array content: " << ar << endl;
    return 0;
}
