As written, there's an …  |

| | CARGO i recommend that you use code tags next time. Secondly instead of converting in an arphadox manner. Why not use the library function. [code] toupper(); [/code] [url]http://www.cplusplus.com/reference/clibrary/cctype/toupper/[/url] The above website will show examples on the usage ;) |
| | [code] reqList = new list<string>[6]; [/code] I doubt this code. [code] list<string> reqList(6); [/code] might be the correct way to do that. |
| | Well, A simple solution would be to read in all the data. Find the person whose data needs to be edited. Then after that. Edit the data. Then Write the file all over again . |
| | Guys instead of USING AN ARPHODOX method to solve your conversion from char to numerical. Why dont you use the atoi() function built in. That way you will not need to care abt any format. [code=c++] string a; unsigned short int Sum=0,i; a="12522"; for(i=0;i<a.length();i++) { string b; b=a[i]; Sum+=atoi(b.c_str())]; } … |

| | You can use strcmp() function to check the strings. Secondly. I would also recommend that you get all the input in lowercase with tolower() function for each character of the string. THis is because ADD!=add!=adD |

FIrstly you are converting the alphabet character 'A' into an int. ANd then secondly after the for loop is done it would just add (a+j) in the … |

| | I am not sure. But [code] tempnum /= tempnum ; [/code] You are dividing a number by itself which would result in being one right. I think it should be [code] tempnum= (tempnum-tempdig)/10; [/code] This way the last digit can be removed . If that is what you want to … |
 | Well . I think : when the compiler starts reading your code. it goes into the (set error message function) and then looks at a class B .. which doesnt exist until then . --------------------------------------------------- Secondly. There is no need for the class A to be in class B. So … |
