C++ Reference: For and While Loops

Video Tutorials

Lesson 16: For Loops

Example 1

// Loop 10 times with the index running from 0 to 9
for (unsigned int uiIndex = 0; uiIndex < 10; ++uiIndex) {
    // Some code
}

Example 2

// Infinite loop
for (;;) {
    // Some code
}

Example 3

// Equivalent to a while loop
for (;!bDone;) {
    // Some code which eventually changes the value of 'bDone'
}

Example 4

// For loop with multiple initializers and updates
for (int i = 0, int j = 5; i  < 10; ++i, ++j) {
    // Some code
}

Lesson 8: While and Do While Loops

Example 1

// Runs as long as done is false
while (!bDone) {
    // Some code which eventually changes the value of 'bDone'
}

Example 2

// Similar to a for loop
int iIndex = 0;
while (iIndex < 10) {
    // Some code
    ++iIndex;
}

Example 3

// Infinite loop
while (true) {
    // Some code
}

Lesson 8: While and Do While Loops

Example 1

// Loop until 'bDone' is true, runs at least once
do {
    // Some code which eventually changes the value of 'bDone'
} while (!bDone);

Example 2

// Infinite loop
do {
    // Some code which eventually changes the value of 'bDone'
} while (true);
