How to generate Numbers automatically within a specific Range?

Lets say we want to print Numbers between 4 and 6, including 4 and 6.

#include<iostream>
using namespace std;
int main()

{
int x;
for ( x = 1 ; x <= 70 ; x++ ) // you can replace 70 with Any Number.
cout<< 4+   rand() % 3 <<endl; // to Produce Numbers between 4 & 6 including 4 and 6.

cout<<endl<<endl;
return 0;
}


Mod of 3 with any random number will give value less than 3 and greater than 0, and by adding any number from 0 to 2 with 4, we get either 4,5 or 6.

Simple!

  1. hi
    sir can you explain these questions of
    function
    Question 1:
    Write a function which receives a float and an int from main( ), finds the product of these two and returns the product which is printed through main( ).

    Question 2:
    Write a function that receives 5 integers and returns the sum and average of these numbers. Call this function from main( ) and print the results in main().

    Question 3:
    A 5-digit positive integer is entered through the keyboard, write a function to calculate sum of digits of the 5-digit number.

    Question 4:
    A positive integer is entered through the keyboard, write a program to obtain the prime factors of the number.

    Question 5:
    Given N and K write a function to compute the Binomial Coefficient. Pass the value of N and K to the function, calculating Binomial.
    [Hint]: Make an additional function of factorial as well. Your main will contain only a single function call.

    N!

    K! (N-K)!
    Question 6:
    Write a function with the name mypower that behaves exactly like pow function of math.h and a function factorial

    Question 7:
    Write a function that receives as input three integer arguments and then circularly shift their values to right. (The change in variables must be permanent) Example:
    If x=5, y=8, z=10 then after circular shift y=5, z=8, and x=10.



    Question 8:
    Write a function to find the binary equivalent of a given decimal integer and display it.

    Question 9:
    Write a function to obtain the first 25 numbers of a Fibonacci sequence. In a Fibonacci sequence the sum of two successive terms gives the third term. Following are the first few terms of the Fibonacci sequence: 1 1 2 3 5 8 13 21 34 55 89...
    Question 10:
    Write a C++ function to evaluate the series
