Implementation of grep command

Write a program to implement grep command. If word matches with any of the file line, then print that line.

#include<stdio.h>
#include<string.h>
int main()
{
	FILE *fp;
	char temp[100],file[32],word[32];
	printf("Enter file name = ");
	scanf("%[^\n]",file);
	fp = fopen(file,"r");
	if(fp == NULL)
	{
		printf("file is not present in this directory\n");
		return 0;
	}
	printf("Enter word to search for = ");
	scanf("%s",word);
	while(fgets(temp,100,fp) != NULL)
	{
		if(strstr(temp,word))
		{
			printf("%s",temp);
		}
	}
	fclose(fp);
	return 0;
}

Note: File name data is present in the current working directory.
