Print string of odd length in ‘X’ format in C Program.

Given with a string program must print the string in ‘X’ format. For reference, see the image given below.

Here, one variable can be used to print from left right(“i”) and other variable can used to print from right to left(“j”) and we can take other variable k which is used for space calculation.

Below is the C++ implementation of the algorithm given.

Algorithm

START
Step 1 ->Declare Function void print(string str, int len)
   Loop For int i = 0 and i < len and i++
      Set int j = len-1- i
      Loop For int k = 0 and k < len and k++
         IF k == i || k == j
            Print str[k]
         End
         Else
            Print " "
         End
   End
Step 2 -> In main()
   Declare string str = "tutorialpoint"
   Set int len = str.size()
   Call print(str, len)
STOP

Example

#include<iostream>
using namespace std;
void print(string str, int len){
   for (int i = 0; i < len; i++){
      int j = len-1- i;
      for (int k = 0; k < len; k++){
         if (k == i || k == j)
            cout << str[k];
         else
            cout << " ";
      }
      cout << endl;
   }
}
int main (){
   string str = "tutorialpoint";
   int len = str.size();
   print(str, len);
   return 0;
}

Output

if we run above program then it will generate following output
