c - File write unexpected output -

i have made program copies text file file. result was, original file contents "this test" new file contents "this test" worked, commented part out , tried make output this. result wanted, original file contents "this test" new file contents,

"t h s  s   t e s t" 

for reason output diagonal , messed up, sure because whitespace character messing up, tried check space, , not move next line when encounters whitespace.

#include <stdio.h>  int main(void){     file *fp = fopen("originalfile.txt", "r");     char buffer[81];     fgets(buffer, 81, fp);     fclose(fp);      //copies file     /*        file *fp2 = fopen("newfile.txt", "w");        fputs(buffer, fp2);        fclose(fp2);      */      //copies moves next line after each character     file *fp2 = fopen("newfile.txt", "w");     int x;     char z = '\n';     int = z;     printf("%d", z);     (x = 0; x < strlen(buffer); x++){         fputc(buffer[x], fp2);         int res = fgetc(fp2);         if(isspace(res) != 0){             fseek(fp2,81,seek_cur);         } else {             printf("yeh got here");         }     } } 

rohan's solution works. have tested in machine, try this:

#include <stdio.h> #include<string.h> int main(void){     file *fp = fopen("originalfile.txt", "r");     char buffer[81];     fgets(buffer, 81, fp);     fclose(fp);      file *fp2 = fopen("newfile.txt", "w");     int x;     (x = 0; x < strlen(buffer); x++){         fputc(buffer[x], fp2);         fputc('\n', fp2);     }     return 0; }
