C fputs() and fgets()

The fputs() and fgets() in C programming are used to write and read string from stream. Let's see examples of writing and reading file using fgets() and fgets() functions.

Writing File : fputs() function

The fputs() function writes a line of characters into file. It outputs string to a stream.

Syntax:

    
        int fputs(const char *s, FILE *stream)

Example:

    
        #include  
            #include  
            void main(){  
            FILE *fp;  
            clrscr();  
              
            fp=fopen("myfile2.txt","w");  
            fputs("hello c programming",fp);  
              
            fclose(fp);  
            getch();  
            }

myfile2.txt

Output

hello c programming

Reading File : fgets() function

The fgets() function reads a line of characters from file. It gets string from a stream.

Syntax:

        
            char* fgets(char *s, int n, FILE *stream)

Example:

        
            #include  
                #include  
                void main(){  
                FILE *fp;  
                char text[300];  
                clrscr();  
                  
                fp=fopen("myfile2.txt","r");  
                printf("%s",fgets(text,200,fp));  
                  
                fclose(fp);  
                getch();  
                }

Output

hello c programming
