C program incrementing variable with for loop

I wish did fix the issue. You're initializing a to 0 when your loop is created( see a = 0 on line 9 of your code snippet). The first iteration will be just that, 0.
code :
#include <stdio.h>

int main(int argc, char* argv[]) {

    int a;

     * RIGHT HERE! 
     * "a" is being assigned the value of 0 for the first iteration, and is incremented each loop
     * until a is no longer less than 10.
    for (a = 0; a < 10; a++) {

        printf("%d\n", a);


    return 0;

Why is for/while loop variable incrementing by 1 after loop exit? Unwanted side effect

I wish this helpful for you When i is 7, the condition i < 8 is still fulfilled, so there is no reason to exit the loop.
It is not very clear to declare the loop variable before the loop and use it afterwards anyway. Rather, consider declaring the loop variable with the loop statement.
code :
int numIterations = 8;
for(int i = 0; i < numIterations; i++) {
    // ...

// continue doing something with numIterations, or numIterations-1

C Program not entering for loop, but incrementing loop index variable?

Hope that helps Here is the COMPLETE text of my program, besides what has been commented out: , Your loop formatting is wrong.
The format for a for loop is:
code :

for(j=0; j++; j<100)
for(j=0; j<100; j++)

How to code a self incrementing loop that carries on from the last value stored when the program is run again vb.net?

Any of those help To achieve this, you can store whatever data you want to store as an application setting.
In visual studio, if you want to add a setting, go to the settings pane of the solution explorer.

In a for loop, is there a difference between pre/post-incrementing a loop control variable in terms of the total quantit

To fix this issue There is no difference. In older compilers, ++counter was faster because it did not create a temporary variable but all modern compilers can optimize that out. For heavy objects with custom (non-inlined) increment operators, ++counter can still be more efficient.
As for when evaluation takes place:
code :
for (initialization; condition; increment/decrement)
    while (condition)

C++ File reading program incrementing variable wrong in loop

I think the issue was by ths following , When you allocate memory for a variable without giving it a value, the value will be a garbage one. Meaning that you can't be sure of it. In C++, you always should initialize your variable.
Morehover, I guess you meant while (!scores.fail()) instead of while (scores.fail())
code :
#include <iostream>
#include <map>
#include <vector>

int main()
    int rangeStep = 10;

    std::map<int, size_t> sortedScores;

    std::vector<int> scores { 76, 89, 150, 135, 200, 76, 12, 100, 150, 28, 178, 189, 167, 200, 175, 150, 87, 99, 129, 149, 176, 200, 87, 35, 157, 189 };

    for (int score : scores)
        ++sortedScores[score / rangeStep];

    for (const auto& element : sortedScores)
        std::cout << "Range [" << element.first * rangeStep << "," << (element.first + 1) * rangeStep << "] => " << element.second << std::endl;

    return 0;
Range [10,20] => 1
Range [20,30] => 1
Range [30,40] => 1
Range [70,80] => 2
Range [80,90] => 3
Range [90,100] => 1
Range [100,110] => 1
Range [120,130] => 1
Range [130,140] => 1
Range [140,150] => 1
Range [150,160] => 4
Range [160,170] => 1
Range [170,180] => 3
Range [180,190] => 2
Range [200,210] => 3
std::vector<int> ReadScoresFromFile(const std::string& p_filename)
    std::vector<int> result;
    std::fstream file(p_filename);
    std::string line;

    while (getline(file, line))
        std::stringstream   linestream(line);
        std::string         value;

        while (getline(linestream, value, ','))

    return result;
