Left factoring in c++
NettetIn this program, an integer entered by user is stored in variable n. Then, for loop is executed with an initial condition i = 1 and checked whether n is perfectly divisible by i or not. If n is perfectly divisible by i then, i will be the factor of n. In each iteration, the value of i is updated (increased by 1).
