I have a text file with some content i need to search the file for a word and have to write the complete line in which my search word is found to another text file.

i am using ifstream to open the file but unable to search the file for the text.

Read a line at time using getline[^], then use string::find[^] to search for the word in the line.

when ever i use getline it shows getline() undeclared identifier

FILE *fp;
fp = fopen("address.txt","a");
char str[1024];
getline(fp,str);

i have these header files
string,iostream,fstream

getline takes an istream object, not a FILE pointer. Create an ifstream instance instead of using fopen
