data written in file is given above. this code is running but just not giving the right number of occurrences of a string

#include<stdio.h>
#include<string.h>
#include<stdlib.h>
#include <ctype.h>

int Search_in_File(char *fname, char *str) {
FILE *my_file;
int sr_num = 1;
int result = 0;
char temp1[512];
int l;

my_file=fopen ("names.csv","r");
if (my_file==NULL){
perror (" empty file ");
return -1;}



while(fgets(temp1, 512, my_file) != NULL) {
if((strstr(temp1, str)) != 0) {
l++;
printf(" match found on line: %d\n", sr_num);
printf("\n%s \n", temp1);


result++;
}

sr_num++;
}
printf(" frequency of occuring is %d ",l);

if(result == 0) {
printf("\n match not found\n");
}


if(my_file) {
fclose(my_file);
}
return(0);
}

int hash1(char *a){
int hash=0;
while (*a){
hash = hash + *a;
a++;
}
return hash;

}


int main(){


FILE * myfile;
char a[256];
char j[50];
char b[5381];
int i,k, result;
myfile=fopen ("names.csv","r");
if (myfile==NULL){
perror (" empty file ");}
else
{
while ( fgets ( a, sizeof a, myfile ) != NULL ){


int i = hash1(a);
if (b[i] != *a)k=1;
if (b[i] == *a){
k++;

while (b[i] !=' '){
i=i+1;
}



}

b[i]= *a;

printf(" %d %d %s " ,i,k,a);
printf("\n");

}





}
printf("enter the name you want to search \n");
scanf("%s",j);

result = Search_in_File("name.csv", j);
if(result == -1)
perror("Error");


return 0;
}

mc Larenc


these are the values in the file now suppose i want to find how many times name mc Larenc occurs in the file i run the above code with these values in temp and it gives me answer 5 that is strstr function writeen above is not comparing two strings its just comparing first two characters and giving answer 5 so it want replacement of the function strstr

@richard temp1 are string values that are being read from a file and str is input string from user whose no of occurrences we need to check in the file

i have written whole code @Cpallini i'm just having problem in comparing the two strings so i posted only this much code.
