4. read in a numbers of line in a file and compute the min, max & mean of each line    bytes.com

You calculate your mean as you go along but the mean needs to be calculated at the end once you know the total value of all numbers and the count of numbers. By contrast you calculate min and max at the end, testing the same value of x repeatedly but you need to calculate min and max as you go along ...

5. reading two numbers in the same line from a file    cboard.cprogramming.com

FILE *pFile = fopen(filename, "r+"); //handle file not existing case .. int line_size = 0; size_t line_buffer_size = 100; char* line_buffer = malloc((line_buffer_size + 1) * sizeof(char)); while ((line_size = getline(&line_buffer, &line_buffer_size, pFile)) != -1) { //tokenize string and get the values you need pch = strtok(result_array[i], "\t"); int col = 0; while (pch != NULL) { pch = strtok(NULL, "\t"); ...

Consider reading the FAQ on how to get a line from the user. You're not seeing the point here: %s stops at white space. A "string" in C is a series of characters terminated by a newline. By definition then, it could include spaces. You don't say if your file has spaces other than the newlines at the end of the ...
