basic C++ question, slighty confused too

[Voli]

I have a question about:

and i only know really basic c++ none of the really fancy stuff :(

How to convert integers into a string/character array?

and

How do I search for specific integers in the string/character array? (all the input is integers)

Any help is appreciated :)

To convert integer to string u can use sprintf
sprintf(arr,"%d",integer);

To search for a integer in string or char array
you have to go character by character and use isdigit to check if it is a number

I guess Raghuram has explained that clearly enough

Assume the following declaration

char str="345633";

you want to search the number 5 in this.

loop through str. Any string in c is a character array.
So str[0]='3', str[1]='4',etc
So, to find the number 5, you have to search for the character '5', ascii value 48+5

If you are using C++, then use a stringstream:

int data = 1234;
stringstream ss;
ss << data;
string str;
ss >> str;
 

and you are done.
