When I read text from a file,Code:while(fgets(buffer,127,pInfile)!=NULL) { for(i = 0; buffer[i]; ++i) { buffer[i] = tolower(buffer[i]); printf("%c",buffer[i]); count[buffer[i] - 'a']++; } }
i don't understand about the second argument of the for loop,
what does it mean for the for loop to run until buffer[i],
i don't understand the meaning of buffer[i] in the for loop argument
because usually it is sth like for(i=0; i<=5; i++)
Please explain me T___T;
