Storing value from txt file (C)

Question

I'm working on a code that has to take a value from a txt file, i have to read it with fgets and the txt file is set like this:
ITEM: 22
i tried doing something like
char line[50];
fgets(line,50,/*nameoffile*/);
if(strstr(line,"ITEM: ")){
/*code*/}
but then i dont know what to do in the if statement.
I'm working on windows,not on code playground.

Answer 1

do you want access 22?
if yes
then you should try this...

char *ptr=strstr(line,"ITEM: ") ;
if(ptr) {
print(ptr+6);
}

/*
strstr = Returns pointer to first occurrence of "ITEM: " in line.
i have stored in a pointer.

In the print statement i have written ptr+6. i set the pointer position to the 6 place from its original position.

and i have choose 6 because of length of "ITEM: " is 6.
