ohh....I didnt include the setprecision and std::fixed. But if I include it, my code still doesnt print right. 500.00 as a string the float just becomes 50000.00

This is exactly what I did in my...

I am trying to convert a string "500.00" into float.

When I use this it produces a string 50000, why does it produce such a result?

atof(bal.c_str());

ok so I am trying to read in a file. Do some string checking. And output the counters. But somehow I think something is wrong with my strcmp. And I do not know where is the problem. Everything...

thanks alot for explaining!

will atoi(text[0]) work too?
because doing atoi("0") is hardcoding....

I got a question about c++ strings.

Let's say string text = "0R14"

and I access each element using text[0],text[1] etc

does text[0] return an integer 0? or a character '0'?

if it doesn't...

i++ or i+= will not work because the compiler doesnt allow such operations for enum iterations

by the way this is my main when I run the program for testing

int main()
{
print_shortest_path(changi, bedok);

system("pause");

}

I am doing a program to print out the shortest path between locations. I implemented it using a 2D array for the adjacency matrix.

However, when I run it and input the start and end locations,...

so C doesnt have bool defined that's why they need to define it like that?

what's wrong with this line when I try to compile in C++?? The src code was originally in C. It gets an expected identifier error with my c++ compiler

typedef enum {false, true} bool;

So basically I am creating a client/server kind of program. The client/user enters a question eg "Who are you? "
The server part receives this and checks it with a txt file and returns eg "I am a...

forgot to mention that in my above post, but i tried putting the braces as you advised too. Both removing and changing the position of the braces resulted in the program doing nothing. Im not new to...

hmm i removed those braces and got the same results as I posted before.

ok so now my code compiles properly. However, it doesnt work. I am able to input a question like How are you?
but nothing else happens. It should be able to create a fork and the server side of my...

the error is the recv_data type is not the same as my vector strings (qns and ans). So I am unable to string compare. And this is kind of a problem for me

So, what Im trying to do here is a client server socket program. The client will ask a question to the server. For example, How are you?
Then the server opens a text file, compares the string from...

thanks for the help so far. I have changed all my test functions and all of them work except for counting the total size of files in bytes. I know that strings do not allow integer calculations. So,...

ok here's my updated and corrected code. Compiles fine. But when I run the command ls -ali | ./a.out in Unix, I get a segmentation error. Am I missing a library?

which is the break the input line into different fields and check only...

oh didnt notice i copied the code twice lol just ignore the copied one

I did a program to read the output of the UNIX command ls -ali

But there seeems to be something wrong with my code and I cant...

ok so i came up with this code, seems that I have a compilation error and I cant seem to figure out why

#include <iostream>
#include <cstring>
using namespace std;

so there is no other functions to find out the file type (dwrx) other than to check the string (dwrx etc...) if im not allowed to use stat functions?

because if this is the situation, and I...

someone help plssss:-/

so to clarify, will mode_t work if I use it with pre defined macros such as S_IFDIR , S_IFLNK , S_IRUSR ?? or is it a must to use them with st_mode??

for example if I wanna do a file checking...

Hi guys I just wanna ask what is the difference between the mode_t and st_mode when using sys/stat.h and sys/types.h libraries. I looked them up google and find most people use st_mode but never...
