Show the following output using one loop. 1, 2, 3, 4, 5 6, 7, 8, 9, 10 Try to achieve the result by forcing the next iteration within the loop […]
Continue ReadingC++: While Loops
Start an integer value at 1024. Loop while it is greater than 0. Print the value (with a newline) and divide it by two each time through the loop. int […]
Continue ReadingC++: Loop Breaks
Show a loop which prints random numbers (each number newly generated each loop) from 0 to 19 (inclusive). If a number is 10, stop the loop after printing it, and […]
Continue ReadingC++: Infinite Loops
Specifically print out “SPAM” followed by a newline in an infinite loop. while (true) std::cout << “SPAM” << std::endl; or for (;;) std::cout << “SPAM” << std::endl; or do std::cout […]
Continue ReadingC++: Do While Loop
Start with a value at 0. Loop while value mod 6 is not equal to 0. Each time through the loop, add 1 to the value then print it. The […]
Continue ReadingC++: Why is one loop so much slower than two loops?
Suppose a1, b1, c1, and d1 point to heap memory and my numerical code has the following core loop. const int n=100000 for(int j=0;j<n;j++){ a1[j] += b1[j]; c1[j] += d1[j]; […]
Continue ReadingC++: Execute Only Part of Loop
Quite often one needs loops which, in the last iteration, execute only part of the loop body. The goal of this task is to demonstrate the best way to do […]
