    Unhappy Probrem With Switch (Another Easy Task):

    Oki I'm trying to lean C so don't blame on me, I'm having problems with this switch, the program itself is useless I'm just trying to learn the language syntax, here goes the code:

    Code:
    #include<stdio.h>
    
    //Dumb Program to Count Digits
    int main(){
    	int c, i, nblanks, nothers, ndigit[10];
    	
    	nblanks = nothers = 0;
    	 for (i = 0;i < 9;i++)
    		ndigit[i] = 0;
    	 while ((c=getchar())!= EOF)
    	 {
    	 switch(c){
    		case:'0':case:'1':case:'2':case:'3':case:'4':
    		case:'5':case:'6':case: '7':case:'8':case:'9':
    		ndigit[c-'0']++;
    		break;
    		
    	    case ' ':
    	    case '\n':
    		case '\t':
    		 nblanks++;
    		break;
    
    		default:
    		 nothers++;
    		break;
    		}
    	 }//switch
    	 printf("Digits = ");
    	 	for (i = 0; i < 10; i++)
    			printf("%d",ndigit[i]);
    		printf("Blanks = %d and Others = ",nblanks,nothers);
    	return 0;
    }//main
    It says I have a parse error before : at line 13, also says that I have unreachable code on the beginning of the switch statement, can you folks helo me?

    It should be case <blah>:, not case:<blah>:. You have extraneous colons lying around.

    You have extra colons, which appears more obviously once the code has been correctly reformatted (I suggest GNU Indent) as follow (not fixed):
    Code:
    #include<stdio.h>
    
    /* Dumb Program to Count Digits */
    int main ()
    {
       int c, i, nblanks, nothers, ndigit[10];
    
       nblanks = nothers = 0;
       for (i = 0; i < 9; i++)
          ndigit[i] = 0;
       while ((c = getchar ()) != EOF)
       {
          switch (c)
          {
          case:
          '0': case:
          '1': case:
          '2': case:
          '3': case:
           '4':
          case:
          '5': case:
          '6': case:
          '7': case:
          '8': case:
           '9':
             ndigit[c - '0']++;
             break;
    
          case ' ':
          case '\n':
          case '\t':
             nblanks++;
             break;
    
          default:
             nothers++;
             break;
          }
       }                            /* switch */
       printf ("Digits = ");
       for (i = 0; i < 10; i++)
          printf ("%d", ndigit[i]);
       printf ("Blanks = %d and Others = ", nblanks, nothers);
       return 0;
    }                               /* main */
    Note that the 'recommenting' has been made by some utility of mine)
