Answer to Question #239457 in C++ for JacksonCrews

Question

Given a string on one line, a second string on a second line, and an integer index, insert the contents of the second string in the first string at the index specified. Then, output the result.

Ex: If the input is:

FuzzyBear

Wuzzy

5

the output is:

FuzzyWuzzyBear

Note: Using a pre-defined string function, the solution can be just one line of code.

#include <iostream>

#include <string>

using namespace std;

int main() {

string workStr;

string otherStr;

int strPos;

getline(cin, workStr);

getline(cin, otherStr);

cin >> strPos;

cout << workStr << endl;

return 0;

}

Answer 1

#include <iostream>
#include <string>
using namespace std;


int main() 
{
	string workStr = "Fuzzy";
	string otherStr = "Wuzzy";
	int strPos=2,i,l=0;

	cout<<"\n\tString-1: "; getline(cin, workStr);
	cout<<"\n\tString-2: "; getline(cin, otherStr);
	strPos=-1;
	while(strPos<0 || strPos>workStr.size())
	{
		cout<<"\n\tEnter Pos. (0 to "<<workStr.size()<<")    : "; cin>>strPos;	
	}


	char temp[workStr.size()+otherStr.size()];
	for(i=0;i<(workStr.size() + otherStr.size());i++) temp[i]=0x20;
	


	if(strPos<=workStr.size()) 
	{
		for(i=0;i<strPos;i++) {temp[i] = workStr[i];	l++;}
		int j=0;
		for(i=strPos;i<(strPos+otherStr.size());i++){temp[i]=otherStr[j]; j++;	l++;}
		for(i=strPos;i<workStr.size();i++) temp[l] = workStr[i]; 
	}
	cout<<"\nNew String: ";
	for(i=0;i<(workStr.size() + otherStr.size());i++)	cout<<temp[i];
	return 0;
}
