To (properly) multiply an string by an integer, you split the string into characters, repeat each character a number of times equal to the integer, and then stick the characters back together. C++ Programming Server Side Programming Multiplication of two numbers a and b yields their product. The character with the highest code point is then added to the output. The numbers may be very large (may not fit in long long int), the task is to find product of these two numbers. Take a as the real part of the first string while b as the imaginary part of the first string. // and add result to previously stored result.
