fputs() function in C


    int fputs(const char *string,FILE *filename);


    const char *string,FILE *filename

Return type: int

Use of function:

In the file handling, through the fputs() function we take the string from the user and store it to the input stream and increments the file pointer indicator for accepting next string input. The prototype of the function fputs() is: int fputs(const char *string,FILE *filename);

It returns the negative value on success and return EOF for failure. Here string is the array of character and filename is the name of the file stream.

fputs() example in C

#include <stdio.h>
#include <stdlib.h>

int main()
    //Initialize the file pointer
    FILE* f;
    //Take a array of characters
    char ch[100];

    //Create the file for write operation
    f = fopen("includehelp.txt", "w");
    printf("Enter five strings\n");
    for (int i = 0; i < 4; i++) {
        //take the strings from the users
        scanf("%[^\n]", &ch);
        //write back to the file
        fputs(ch, f);
        //every time take a new line for the new entry string
        //except for last entry.Otherwise print the last line twice
        fputs("\n", f);
        //clear the stdin stream buffer

    //take the strings from the users
    scanf("%[^\n]", &ch);
    fputs(ch, f);
    //close the file after write operation is over

    //open a file
    f = fopen("includehelp.txt", "r");
    printf("\n...............print the strings..............\n");
    while (!feof(f)) {
        //takes the first 100 character in the character array
        fgets(ch, 100, f);
        //and print the strings
        printf("%s", ch);
    //close the file

    return 0;
