How to save entered strings and integers in C -


can me on code. should when enter "create 6 5" supposed create 6x5 rectangular shape *'s, not show yet unless entered "show".

this code i'm working on, not correct yet, still figuring out how it.

i'm new in programming.

char s[100];     char *s1 = "show";     char *s2 = "create";   int main() {     int zwidth = 0, zheight = 0, zloop = 0, aloop = 0;          {     scanf("%s %d %d", &s, &zwidth, &zheight);      }     while (strcmp(s1, s) != 0);      if(strcmp(s2, s) == 0)     {     //to draw first horizontal line      for(zloop = 0; zloop < zwidth; zloop++)      printf("*");      printf("\n");       //drawing vertical lines      for(zloop = 2; zloop < zheight; zloop++)      {          printf("*");          for(zloop = 0; aloop < zwidth-2; aloop++)              printf("*");              printf("*\n");      }       //last horizontal line      for(zloop = 0; zloop < zwidth; zloop++)      printf("*");      printf("\n");     }       return 0; } 

#include <stdio.h>  enum command_state {     show, create, quit, help, invalid };  char command_line[100]; const char *show   = "show"; const char *create = "create"; const char *quit   = "quit"; const char *help   = "help"; const char *qmark  = "?";  enum command_state command(void){     if(fgets(command_line, sizeof(command_line), stdin) != null){         char operation[16];         sscanf(command_line, "%15s", operation);         if(!strcmp(operation, show))             return show;         else if(!strcmp(operation, create))             return create;         else if(!strcmp(operation, quit))             return quit;         else if(!strcmp(operation, help) || !strcmp(operation, qmark))             return help;         else             return invalid;     }     return quit;//input eof }  int main(void){     int rwidth = 0, rheight = 0, aloop = 1;     while(aloop){         switch(command()){         case show :             if(rwidth == 0 || rheight == 0)                 printf("execute create required before\n");             else {                 int h, w;                 for(h = 0; h < rheight; h++) {                     for(w = 0; w < rwidth; w++)                          printf("*");                      printf("\n");                 }             }             break;         case create :             if(2!=sscanf(command_line, "create %d %d", &rwidth, &rheight) ||               rwidth < 1 || rheight < 1){                 rwidth = rheight = 0;                 printf("invalid create command\n");             }             break;         case quit :             aloop = 0;             break;         case :             printf(                 "help or ? : this\n"                 "create w h: set size of rectangle width ,  height\n"                 "show      : draw filled rectangle\n"                 "quit      : end of program\n"             );             break;         default :              printf("invalid command\n");         }     }      return 0; }

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
