Search string in file (C)
- by chutsu
So my code isn't working...
test.c:27: warning: passing argument 1 of ‘search’ from incompatible pointer type
which is the fgets line.
My code opens a file, reads the file line by line, and I'm trying to create a "search" function that will return a value that indicates whether that string is found on that line of the file.
My ultimate goal is to achieve a search and replace program. But one step at a time eh?
this is what I have so far:
#include <stdio.h>
#include <string.h>
int search(const char *content[], const char *search_term)
{
int t;
for(t=0; content[t]; ++t){
if(!strcmp(content[t], search_term)){
return t; // found
}
}
return 0; // not found
}
int main(int argc, char *argv[])
{
FILE *file;
char line[BUFSIZ];
int linenumber=0;
char term[20] = "hello world";
file = fopen(argv[1], "r");
if(file != NULL){
while(fgets(line, sizeof(line), file)){
if(search(line, term) != -1){
printf("Search Term Found!!\n");
}
++linenumber;
}
}
else{
perror(argv[1]);
}
fclose(file);
return 0;
}
