C Count the number of line occurences

[hexes]

Basically I am asked to reinvent the wheel a.k.a. the uniq commmand. I have to write a code that returns the number of occurence of each line in a file. I've done it a lot of times in Python and Java with a simple

for line in file
    if given_line == line;
    count += 1

but I am starting to think that there is no magic thing as

for...in...

in C. I know how to get the total number of lines with

while (!feof(f)){
    fgets(line, sizeof(line), f);
    count += 1;
    {

So I am very much confused. I simply want to figure it out now so I will not be stuck on such a newbie problem in the future. Thanks to everybody in advance.

What exactly is the confusion? If you are able to extract lines, use strcmp() to compare strings. Is this what you wanted? Maybe i didn't completely understand your question.

strcmp will not do good, u have to use strstr() function with loop and if condition which say "strstr(s1,s2)==null" to count the given string line in the file,strstr is available in string.h

If you want to count exact full lines then strcmp() is better. If you want to count lines containing a substring then strstr() is better. The two accomplish different goals.
