Are you trying to add the individual digits or read something into a very large number? That is, are you reading numbers from 0 to 9 and adding these, or are you trying to read a very large number into a 256-bit value (or something big like that)? If you're merely adding digits, a "char" variable type is all you need ... |

Okay... I'm trying to read a map file in integer by integer ignoring commas and newlines and this is the code I've written so far: Code: void LoadWorld (const char* fn) { FILE *f; if ((f = fopen(fn, "r")) == NULL) return; for (int y = 0; y < MAP_H; ++y) { for (int x = 0; x < MAP_W; ) ... |

Use a good sized char array[100] or so, and fgets(array, sizeof(array), filePointer), to put one row of data into the char array. Now, in a for loop from array[0] to array[strlen(array)], count up your spaces and add 1 - that is how many numbers you have in that row. now malloc() memory for that size row, and sscanf() your numbers into ... |
