Question

this program accepts user input and saved to a char array. Then creates a file and put those texts to the new file. Problem is, it can only copy the part before space.
Current Output : “how to read” –> “how”

#include <stdio.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <unistd.h>

int main(int argv, char *argc[]){
    int fd;
    char buffer[100];

    printf("Type your text : ");
    scanf("%s",&buffer);

    fd=open("menew.txt",O_CREAT|O_WRONLY|O_EXCL,S_IRUSR|S_IWUSR|S_IRGRP|S_IWGRP|S_IROTH);
    if(fd<0){
        printf("file already exist!\n");
        }else printf("file created!\n");

    fd=write(fd,buffer,20);
    if(fd<0){
        printf("error on writing...\n");
        }else printf("successfully written!\n");

    close(fd);
    return 0;
}

Finally I found the solution!!!
Use gets(buffer); instant of scanf("%s",&buffer);
