How to treat characters in a char array like integers?

[thejwal pavithran]

hey guys i have a simple function which reads in two integer arrays and outputs the number of same elements in the 2 arrays.

eg:
input:
{11,22,12,13}
{44,55,22,11}

the output will be 2 here.

my function prototype is:

void compare(int list1[],int list2[]);

but theres a glitch.

the modules which call the function pass the lists as strings.

So now i should rewrite the function and the prototype would be:

void compare(char* input1,char* input2);

I have absolutely no idea on how to compare two integers this way. can Somebody please tell me how to compare two integers if they are in a string?.

initially input1 and input2 would give '{' on derefencing

Use this :

void rolling_dice(char*input1,char*input2)
{
//write code here
}

You are better off using strtol rather than atoi.
