Answer / Somdutta Singh

Here's a simple example of C code to search for a specific string within a .txt file using the fopen(), fread(), and strstr() functions. Note that this code assumes that the file is present in the current working directory:
1. #include <stdio.h>
2. #include <string.h>
3. int main(int argc, char *argv[]) {
4. FILE *file;
5. char filename[] = "example.txt";
6. char line[100];
7. char target[] = "keyword"; // replace 'keyword' with your search term
8. if ((file = fopen(filename, "r")) != NULL) {
9. while (fgets(line, sizeof(line), file) != NULL) {
10. if (strstr(line, target) != NULL) {
11. printf("Found the keyword in the file.n");
12. break;
}
}
13. fclose(file);
14. } else {
15. printf("Unable to open the file.n");
16. }
17. return 0;
18. }
