 String length

   The given program is for the find the length of the given string.

                           #include<stdio.h>
                            int stringlength(char *);

                            main()
                            {
                                  char source[100];
                                     int length;

                                    printf("Enter String\n");
                                    scanf("%[^\n]",source);

                                       length = stringlength(source);

                                      printf("The length of the string is : %d\n",length);
                             }
                             
                               int stringlength(char *str)

                              {
                                     int count = 0;
                   
                                          while(*str != '\0')

                                               {
                                                     *str++;
                                                       count++;
                                               }
                                   return count;
                               }

                 Output:
                               Enter String
