Find and Replace words in a paragraph || C++ function || Char array practice

Limitations :

• Hard coded paragraph
• The word to be found and to be replaced with must be of the same lengths.
• For those who have no idea of pointers, simple char array is used hence hard coded the size as well.

Code:

   

#include <iostream>

#include <conio.h>

using namespace std;

void mySearch(char para1[], int size, char find[], int fsize, int &index, int x)  //Search function

{

index = -1;

int i = 0;

if (find[i] == para1[x])   //para1 is the array that contains paragraph

{ 

                  //find contains the word to be found

int j = x, flag = 0;

for (i = i + 1; i < size && find[i] != '\0' && flag == 0; i++)

{

x++;

if (find[i] == para1[x])

{

;

}

else

flag = 1;  //if the complete word is not found ... breaks the loop

}

if (flag == 0)

{

index = i;  //if the complete word is found

}

}

}

char toReplace(char replace[], int size, char para[], int rsize, int index, int x1) //this function replaces

{

int i = index;

para[i] = replace[x1];  

return para[i];

}

int main()

{

char para[400] = "Cheating is the getting of a reward for ability by dishonest means or finding an easy way out of an unpleasant situation. It is generally used in situations to gain unfair advantage in a competitive situation. This broad definition will necessarily include acts of bribery, cronyism, sleaze, nepotism and any situation where individuals are given preference using inappropriate criteria.";  //hard coded para

cout << para << endl;  //displaying paragraph (optional)

char find[10], replace[10];

cout << "Find : ";

cin >> find;

cout << endl << "Enter the word to replace with : ";

cin >> replace;

cout << endl;

int index = 0, j = 0;

char w;

for (int i = 0; para[i] != '\0'; i++)

{

mySearch(para, 400, find, 10, index, i);

if (index != -1)

{

for (j; replace[j] != '\0'; j++)

{

w = toReplace(replace, 10, para, 400, index, j);

cout << w;

index++;

i++;

}

i--;

j = 0;

}

else

cout << para[i]; //displaying paragraph

}

system("pause");

return 0;

}
