Variable doesn't get updated when I run a loop

Question

I want to iterate through a word and print each of its characters, together with its ASCII number.

I've tried

#include <iostream>
#include <stdio.h>

using std::cout;

int main()
{
    char cWord[30] = {"Larissa"};
    int iCounter = 0;
    char cLetter = cWord[iCounter];

    for (iCounter = 0; iCounter < 5; iCounter++) {
        printf("%c == %d \n", cLetter, cLetter);
    }
}

but that just prints L == 76 five times. I suppose that means the cLetter variable doesn't update as I run the for loop, but I don't understand why.

Answer 1

You need to update cLetter in the loop, there's no magic connection to earlier code. Might as well move cLetters scope to inside the loop as well. Try

for (iCounter = 0; iCounter < 5; iCounter++) {
        char cLetter = cWord[iCounter];
        printf("%c == %d \n", cLetter, cLetter);
    }

Here, iCounter is updated each iteration, and therefore cLetter is too.

Answer 2

You're only assigning cLetter once, outside of the loop, so it remains constant throughout the loop iterations.
