c - Can't take input in a string -


in program, i'm not able input in string c[] (in add_diary() ) using fgets() or gets(), program skips input process, please tell me doing wrong. can't started. in diary important thing write , thing 'you can't write, cuz fgets() isn't working'.

    #include <stdio.h> #include <stdlib.h>  void access(); void diary_main(char user[],char pass[]); void diary_login(); void add_diary(unsigned dd, unsigned mm, unsigned yy); void add_entry(unsigned choice); void del_entry(unsigned dd, unsigned mm, unsigned yy); void update_entry(unsigned dd, unsigned mm, unsigned yy); void logout();  void main() {     access(); }  void access() {     char password[10],username[20], ch;     int i;     printf("enter user name: ");     gets(username);     printf("enter password (8 characters):");     for(i=0;i<8;i++) {             ch = getch();             password[i] = ch;             ch = '*' ;             printf("%c", ch);      }      password[i] = '\0';      /*printf("\nyour password :");      for(i=0;i<8;i++) {     printf("%c", password[i]);*/     diary_main(username, password); }  void diary_main(char user[],char pass[]) {     /*file *fptr;     //char file_name[10];     //sprintf(file_name, "user%s.txt", user);     fptr = fopen("login.txt", "w");     fprintf(fptr,"\n%s",user);     fclose(fptr);*/     diary_login(); }  void diary_login() {     unsigned choice;     printf("\nenter choice\n");     printf("1. add diary entry\n");     printf("2. delete diary entry\n");     printf("3. update diary entry\n");     printf("4. logout\n");     printf("5. exit\n");     scanf("%d", &choice);     if (choice == 1) {         add_entry(choice);     }     else if (choice == 2) {         add_entry(choice);     }     else if (choice == 3) {         add_entry(choice);     }     else if (choice == 4) {         logout();     }     else if (choice == 5) {         exit(1);     }     else {         //printf("%d", choice);         printf("enter correct choice");         diary_login();     } }  void add_entry(unsigned choice) {     unsigned dd, mm, yy;     printf("enter date (dd/mm/yy):");     scanf("%u/%u/%u", &dd, &mm, &yy);     //printf("%u/%u/%u", dd, mm, yy);     if ((dd>31 || mm>12) || (dd>29 && mm == 2) || (yy!=17)) {         printf("\nenter correct date\n");         add_entry(choice);     }     else {         //printf("else");         switch(choice) {             case 1: add_diary(dd, mm, yy);                     break;             case 2: del_entry(dd, mm, yy);                     break;             case 3: update_entry(dd, mm, yy);                     break;         }     } }  void add_diary(unsigned dd, unsigned mm, unsigned yy) {     //printf("add_diary");     long file_extra;     char file_name[50], c[5000];     file *fptr;     file_extra = (((dd*100)+mm)*100)+yy;     sprintf(file_name, "diary%ld.txt", file_extra);     fptr = fopen(file_name, "w");     /*if(fptr == null){        printf("error");        exit(1);     }*/     printf("\nstart writing diary..\n");     scanf("%s", c);     //fgets(c, sizeof(c), stdin);     //gets(c);     fprintf(fptr,"%s",c);     fclose(fptr); }  void del_entry(unsigned dd, unsigned mm, unsigned yy) {      long file_extra;      char file_name[50];      file_extra = (((dd*100)+mm)*100)+yy;      sprintf(file_name, "diary%ld.txt", file_extra);      int status;      status = remove(file_name);      if( status == 0 ) {         printf("entry deleted successfully.\n");      }      else {         printf("unable delete file\n");     } } void update_entry(unsigned dd, unsigned mm, unsigned yy) {     long file_extra;     char file_name[50], c[5000];     file_extra = (((dd*100)+mm)*100)+yy;     sprintf(file_name, "diary%ld.txt", file_extra);     file *fptr;     fptr = fopen(file_name, "w");     printf("\nstart editing diary..\n");     scanf("%s", c);     //fgets(c, sizeof(c), stdin);     //gets(c);     fprintf(fptr,"%s",c);     fclose(fptr); } void logout(){  }

from understanding how scanf works:

let's have them input "hello world", brought in "hello world\n". can work around selecting n-1 in array ('\n') , replace terminating ('\o').

python - How to insert QWidgets in the middle of a Layout? -

Image
i'm using qt framework build graphical user interface. use qgridlayout position qwidgets neatly. gui looks this: my application regularly adds new widgets gui @ runtime. these new widgets not added @ end of qlayout, somewhere in middle. the procedure bit cumbersome. applied on figure above, need take out widg_c , widg_d , ... qgridlayout. next, add widg_x and widg_y , , put other widgets again. how remove widgets qgridlayout: for in reversed(range(mygridlayout.count())): self.itemat(i).widget().setparent(none) ### as long you're dealing small amount of widgets, procedure not disaster. in application display lot of small widgets - perhaps 50 or more! application freezes second while procedure ongoing, annoying user. there way insert widgets somewhere in qlayout, without need take out other widgets? edit: apparently solution qvboxlayout simple. use function insertwidget(..) instead of addwidget(..) . docs can found link: http://doc.qt.io/qt-5/qboxlayou
