# Divide a string in N equal parts

StringViews 1703

## Write a program to divide the given string into N equal parts. (N is input)

### Examples

a) Input string : “stringlength”, N = 2
Output :
string
length

b) Input string : “tutorialcup”, N = 3
Output : Invalid input!
Because, string cannot be divided into N equal parts.

## Algorithm

a. Get the size of the given string using strlen() and store in length.

b. If length % N is not equal to zero, print invalid input. Because, string cannot be divided into N equal parts for given N.

c. Get size of each part, part_size = length/N

d. Run loop through the given input string. In this loop, after printing every part_size characters use separator \n or endl.

## C++ Program

```#include <bits/stdc++.h>

using namespace std;

//Function to divide into N equal parts
void divideString(char *string, int N)
{
int length = strlen(string);
//checking if string can be divided in N equal parts
//If not print invalid input
if (length%N != 0)
{
cout<<"Invalid Input!"<<endl;
return;
}
//size of parts
int part_size = length/N;
for (int i = 0; i< length; i++)
{
if (i%part_size == 0)
{
//Next line(seperator)
cout<<endl;
}
cout<<string[i];
}
}

int main()
{
//Input string
char string[] = "stringlength";
cout<<"Input string: ";
for (int i = 0; i < strlen(string); ++i)
{
cout<<string[i];
}
int k;
cout<<"\nEnter the value of N: ";
cin>>k;
divideString(string, k);
return 0;
}```
