Thread: Convert data from file into a matrix

hey there
i need to convert data from a certain file into a matrix, in order to that matrix be a "labirinth" (i'm working on a project that trys to simulate a labirinth game)
my objective here is to read a file, get his content, and then pass it to a matrix that i have denominated as "char * * matrix;"
so, i'm gonna show you my code so you can understand better:

Code:

                
               void main(){

                int c;
                fp = fopen(mapa,"r");				
	if (fp == NULL){
	printf("Can't open %s\n",mapa); 
		exit(0);
	} 
                c = getc(fp);
                while(c != EOF ){
		putchar(c); 
		c = getc(fp); 
		}

now, someone told me that i should do this:

Code:

                 matrix = (char **)malloc(nr_lines * sizeof(char*));
		for (line = 0; line < lines; line++){
		matriz[line] = (char*)malloc(nr_columns * sizeof(char*));
	} // don't worry, i've already denominated lines, columns etc

so, after this, if this 2nd code is right, my matrix positions (x / y) will be the same as the file i've read?
if not, what better way should i do??
thanks in advance,
i really would appreciate it

I was expecting something like "see my avatar" :-D
