Array: Difference between revisions

We wish to open a text file and compute letter frequency

 

/* declare array */

int frequency[26];

/* declare a computed index */

int ch;

any_text = fopen ("a_text_file.txt", "rt");

/* init the freq table: */

for (ch = 0; ch < 26; ch++)

frequency[ch] = 0;

ch = fgetc(any_text);

while (!feof(any_text)) {

frequency[ch-'A'] += 1;

ch = fgetc(any_text);
