How to Divide a string into N equal parts in C++
In this tutorial, we will learn how to divide a string into N equal parts in C++. Also, we have given a string and value of N and our task is to divide this string.
For example:
- Given string: “Better to reduce time complexity”
- Given the value of N= 4
- So, we have to divide this string into 4 equal parts.
- Output:
Better t o reduce time co mplexity
Approach:
To illustrate:
- Firstly, we will get the size of the string over here.
- Now, to get the size, we will include string.h header file.
- Further, we will get the size of the part.
- The size of the part is:
size_of_part=total_string_length/N - Finally, iterate through input string.
- If the Index number becomes multiple of size_of_part, then put a separator over there that is (\n).

Divide a string into N equal parts
Implementation:
#include<iostream> #include<string.h> using namespace std; class separator { // Function for N equal parts public: void separatestring(char str[], int n) { int size_of_str = strlen(str); int i; int size_of_part; // Check for the string if it can be divided or not if (size_of_str % n != 0) { cout<<"Invalid"; return; } // Get the size of parts to get the division size_of_part = size_of_str / n; for (i = 0; i< size_of_str; i++) { if (i % size_of_part == 0) cout<<endl; cout<< str[i]; } } }; int main() { separator s; char str[] = "Better to reduce time complexity"; // Print 4 equal equal parts s.separatestring(str, 4); return 0; }
Output Explanation:
INPUT: "Better to reduce time complexity" OUTPUT: Better t o reduce time co mplexity
This is how we can divide a string into n equal parts in C++.
