We know the pre-defined function str_repeat();. Now how to make our own user defined function that works exact same as str_repeat. For eg str_repeat("John ",10); ( this will print John 10 times ).
Help will be appreciated .

Function modulo is easy.
For example 14 modulo 3. We must find number, which is smaller than 14 (<14), can be divided ( /) and it will be rational number (1, 2, 3... Not numbers like 3,123). It's 12 (12/3=4). Then we just subtract 14 and 12 (14-12). It's 2.

using a while loop create a guessing game program that keeps asking the user to enter a number until the user enters the number 7. You will need to create and initialise an int variable to zero. You can then use this variable as the condition in your while loop ( while the number is not equal to seven) Then in the while loop ask the user to enter a number and store the number entered in the number variable that is in the conditions of your loop.
