How to find a character string within a string? - string

Question

It's only every once in awhile that I have to write in c++. My problem is how do you find a character string within a string? Then save that line, and then look for a set of numbers in that line. For example I have a text file that looks like this.
Address Length Name
87623498 2 dog
12345678 4 cat
98737289 1 bird
I want to search for "cat" and then store the numbers associated with it (12345678) and (4) to different variable names. Here is some code I have written, but it's not close to being correct. I have an .exe that calls this DLL. Any help is appreciated!
`
#include
#include
#include
#include
#include
char* File_Path; //Path is sent by another program
char* Name; //value is being sent by another program
unsigned long Address;
int Length;
int found = 0;
{
using namespace std;
std::string Line;
std::ifstream infile;
infile.open (File_Path);
if (infile.is_open())
{
std::ofstream outfile;
outfile.open ("C:\\debug\\test.txt")
while (infile.good() && found == 0)
{
std::getline(infile,Line);
//if (Name is within Line){
/*I want to say IF char* Name = a part of the string line
ie. Name = cat and the string Line is (12345678 4 cat)
Then store the number (12345678 = Address), and
(4 = Length) I hope that makes sense :/
*/
outfile << Line; //output the stored line for debug
outfile << address; //output the stored address for debug
outfile << length; //output the stored length for debug
found = 1;
}
outfile.close();
infile.close();
}
return 0;
}

Please help! Thank you!
