C function that counts lines in file

Question

When I try to run my program, I get the wrong number of lines printed.

LINES: 0

This is the output although I have five lines in my .txt fi

Answer 1

Here is complete implementation in C/C++

#include 

void lineCount(int argc,char **argv){

        if(argc < 2){
             fprintf(stderr,"File required");
             return;
        }
        FILE *fp = fopen(argv[1],"r");



        if(!fp){
            fprintf(stderr,"Error in opening file");
            return ;      
        }

        int count = 1; //if a file open ,be it empty, it has atleast a newline char
        char temp;

        while(fscanf(fp,"%c",&temp) != -1){
                if(temp == 10) count++;
        }

        fprintf(stdout,"File has %d lines\n",count);
   }

int main(int argc,char **argv){

        lineCount(argc,argv);
        return 0;
}
