I've recently refreshed my mac by reinstalling the operating system. Uploaded the previous C and C ++ source scripts I was working with but when I go to compile them through the bash terminal it says command not found? Im not sure whats going because I thought that all the gcc files were already available? What am I messing here.
View 5 Repliesso i want to make a terminal for my website and BHXSpectre recommended cgi (which i love... c++ web design. just one more reason to not use any other language). anyways, im wondering how would i generate the html for the base of the terminal? ie just the window that i will be writing to
View 2 Replies View RelatedI wanted to make the terminal screen bigger in my NCurses program. Let's say if the defaults are 25 LINES and 80 COLS, I want to set them to 40 LINES and 120 COLS.
I've tried resizing all windows, but that did not work, because the actual terminal (console) was not resized. Then I found functions resizeterm and newterm, but they did not work. As far as my understanding goes resizeterm only updates NCurses information with the current configuration, while the window itself is not actually modified.
NCurses man page wrote:The function resizeterm resizes the standard and current windows to the specified dimensions
If I haven't made myself clear ( I sometimes make a mess of things... ), another example would be that I want my program to be fullscreen when I start it. Is this possible? It should be, I found a fullscreen NCurses program once, but the code was too confusing for me to understand.
Having read about things like SIGWINCH, I assume you must define a method for resizing the terminal screen yourself, I don't know where to start?
1. What is dll and lib?
2. How do I make dll and lib using g++ command prompt?
Also, how do I link libraries using g++?
Any good websites that covers my questions,
I am looking to make a program for C++ that has a GUI other than command prompt. The program I am trying to create will ask certain questions and display the results at the end after all questions are asked and have 2 copies of the results one over the other that can be printed as a receipt. Basically I am wondering can I do this using C++. Also I want another GUI other than command prompt as well. Something close to what windows uses if possible.

Basically I have it so the snake moves like the traditional snake in the game, when it eats the food once it grows. However when it eats the food a second time the game crashes. I think I have narrowed the issue down to the grow array that I have (below) but I am not sure if the issue could be a result of something else.
Grow Array
cord growArray (cord *p_values, int *size)
{
*size = *size + 1;
cord *p_new_values = new cord[ *size ];

I'm new in C++ and sure - I'm learning it.
But - just interesting - how next bash function can't looks like in C++?
This code used to check array of system global variables:
Code:
#!/usr/bin/env bash
# defining and fill array
variables=( [1]=$sysvar1
[2]=$sysvar2
[3]=$sysvar3
[4]=$sysvar3
)
# function
checkvars () {
[Code]...
# start function with array as argument checkvars "${variables[@]}" It's simple enough and I hope C++ code will not be too complicated for me to understand it :-)
P.S. Goal of post - not really made some job for me - but show an example of some C++ code, which I'll can sort out and compare with bash code. Some explanations will be nice.
What does echo in a bash script mean?
The code I'm trying to understand says:
for((m=0; m<1;m++))
do
#assign the correct mechanism to run
RMFilename=${Mechanisms[m]}

but according on several sources, some terminals suport more colors.Is there any way to determine how many colors the current terminal supports?
I am using Xcode to do c++ programming and I have a c++ code, with different input arguments. I want to achieve that in Xcode, I could run multiple simultaneous running of my c++ code. However, the current problem is that once one code finishes, its terminal window automatically closed and I do not have time to look at its result. Thus computer time is wasted. Is there a way to run multiple same c++ code with different arguments input?

a) Write a C-program that creates a chain of 10 processes and prints out their process ids and relationships. For example, process 1 is the parent of process 2, process 2 is the parent of process 3, process 3 is the parent of 4 and so on. Each child has to print out all her ancestors identified by the process ids.
b) Write a C-program that creates a fan of 10 processes. That is, process 1 is the parent of prcocesses 2, 3, 4, 5, 6 and so on.

View 9 Replies View RelatedI'd like to add a 'command' to my C program. For example if someone types 'get out' it closes the shell and quits. I want the 'get out' command to work like 'exit'. How do I write a code like this

The aim is to have the function return the number of arguments made after assigning each of the arguments to a c string stored in an array of five pointers. This is how I declare this:

char s1[300];

I'm trying to read in a file specified in the command line but I'm having some trouble. The command line entry specifies the inputfile preceded by '<' and the output file preceded by '>' like so
./program -v < input_file.cmd > output_file.cmd
This is what I've got so far.
int main(int argc,char* argv[]){
string strv="-v";
string input="<";
string output=">";
string str;
string input_file;
const char* in=input_file.c_str();
[Code] .....
This compiles ok, but when i run it using :
./program -v < test1.cmd
I get a segfault, if i cout argc it returns '2' where i would expect for this command line entry, I 'd get 4.
I'm not yet outputting to file, just to the screen so im not specifying an output file yet.
