    a sentence is read using fgets(); and stored in an array, then the words need to be seperated and the shifted 3 places right in the ASCII code and then put back into the array then capiatlise the words. all other symbols left unchanged.
    i got problems in seperating the words. only the first word is coded in my program.
    please check my code
    thanks...
    note : my capitalise function is not done yet

    Code:
    #include<stdio.h>   // FIX THE BBBBBBBBBBBBUUUUUUUUUUUUUUGGGGGGGGGGGGGGG
    #include<string.h> //  FIX THE bug..............
    
    void read( char secret[]);
    void convert(char secret[],int ascii[],int l);
    void capitalise(char secret[],int ascii[],int l);
    
    int main()
    
    {
        
    char secret[35];
    int l,i,k=0;
    int ascii[35];
    
     read(secret);   
      
                                               // printf("%s\n",secret);   
     l = strlen(secret);   
                                               // printf("%d",l);    
     l = l - 1;   
       
     convert(secret,ascii,l);
    
                                     //   printf(" %c \n",secret[4]);
    
     for(i = 0;i < l;i++);
      {
       if( (ascii[i] == 32) || (i == (l - 1)) )
        {
                                               //  printf("%d\n",i);
          
          while( (k <= i) && ascii[k] >= 97 && ascii[k] <= 122)
          {
           ascii[k] = ascii[k] + 3;
           
           secret[k] = ascii[k];
          
           k = k + 1; 
          
          }
        k = i + 1;
        
        }
            
      }
                                       //  printf("%d",i);
                                         printf("%s\n",secret);
    // capitalise(secret,ascii,l);
     
    return 0;    
        
    }
    
    void read(char secret[] )
    
    {
     printf("Enter the secret to be CIPHERED.... : \n");
    
     fgets(secret,35,stdin);       
        
    return;    
        
    }
