C :: Clrscr Function In Code Block
May 1, 2014I start working on CodeBlocks and stuck in a situation. The situation is that I want to clear my output screen every time the main function calls some other functions. To do that I use clrscr() function but its not working. After spending some times on web, I found that its a non-standard function so this extension is not used by the new compiler's. Another thing I find to use < cstdlib > library. But unfortunately it do works only for C. It works for C++.

Feb 3, 2014I just want my program to run continuously until someone enters 0 to exit it. I tried doing while(x=1) and looping my entire block of code. Also there is a switch one is a for one is a while loop both doing the same function. I have basic error checking and whatnot.
/*This is a program that gets a user to input a starting and ending value.
The code then prints the number ie 1 and 5 would be (1,2,3,4,5) and all the squares and cubes.
There is a case statement asking weather you want to run it as a for or as a while loop.
The choices are case sensitive.

C++ :: Control Execution Of Code Block By Entry
Apr 25, 2013I have a program including several code blocks in the following simplified structure:
int main() {
// block A
if(a > 0) {
}
// block B
if(a > 1) {
} }
Block A and B should be executed separately, according to entry from keyboard. For example, if entry "1", block A will be executed and block B will be ignored; if entry "2" the inverse will happen.
I can control the execution of these two blocks through macro but the code will be separated during compilation. But is there a way to control them without using macro?
C++ :: Shortcut For Commenting Out A Large Block Of Code

C Sharp :: Displaying Text File Block By Block In C#
Dec 21, 2012I have a text file that is divided into blocks:
#1
1:animal
2:food
3:moves
4:oxygen
#2
1:eats:2
2:breaths:2
3:can:1
4:is a:1
#3
1:1:2
1:3:3
1:2:4
And the following program that displays block by block:
StreamReader streamReader = new StreamReader("G:LAB123LABWORK2.txt");
int block = 0;
while (!streamReader.EndOfStream) {
string line = streamReader.ReadLine().Trim();
if (line.CompareTo("") == 0)
[Code] .....
My problem is am supposed to add a verification code so that if i put a string e.g 1:?:? it returns the block where the string is found and gives of all possible answers.
Attached Files : LABWORK2.txt (240 Bytes)
C/C++ :: Output To File Is In Hex Code
Apr 2, 2014Here is program I have written which reads the destination, then finds it from a separate file, and reserves the information on a different file. But the reserved file has hex code information, how can I output my result to the file in normal alphabet/number/symbol characters? I've tried fputs,fprintf, and fwrite , and all give me the same result. The array c, is the one to be written to file.
void main {
FILE *afile = fopen("flightrecord.txt","r");
int i=0,j=0,k=0,z=0,y=0,sum=0,seat=0,g=0;
char destination[10],a[1000],c[1000],b[1000],name[100],last_name[100],c_number[15],plane[]={'P','6','2'};

Mar 27, 2014I will keep this simple as I have the code written for my testing software program, I just want to add a feature of randomly generating the answer choice output order, I do not want to randomly output the full questions, but instead the choices (answers to the question), for example =
#include <string>
#include <iostream>
#include <limits>
cout <<" " << endl ; \ space
[Code] ....
As you can see I would like to output the answers, choices randomly as in answer choice 3 will appear at the top instead of 1. and so on, it doesn't matter if the numbers move with the txt as the numbers beside the
questions are txt.
It's a 32bit console application.
C :: How To Send Results Of Code To Output File And Then View It
Jan 18, 2015In this one program (3 body problem), there are 6 inputs that are scanned (mass, velocity and position of the 2 bodies) and these inputs are computed to arrive at values for x, y and time for the third body. There is a working code that for of extremely small time steps, i.e over 5000 iterations, it produces values for x and y positions of the third body.
I believe this info is sent to an output file since there is a:
FILE* output=fopen("results.out", "w");
I want to play around with the code, insert different values for mass and velocity of the two bodies, but I don't know how to view the results? Im guessing I need to create a results.out file somewhere, but how do I go about doing this?
Do I need to assign memory to the results and then forward that to the output file somehow?
Here is the code : 3body.c
I have a compiler and what not, I'm just unsure how i can get these results out is all.

I think the error is the changing value of x after a round of for loop.

C/C++ :: Program To Find Index Of Character In A String Gives Incorrect Output
Oct 28, 2014I've been typed out a C program to let the user define the size of their string , and key in characters for this string , the program would then prompt the user for a character to search for in the string and return it's index value. Eg. Index of c in abc is 2. My code is as shown:
#include<stdio.h>
#define SIZE 20
int search(char x[SIZE+1] , int n , char s);
int main(void){
char x[SIZE+1] , s;
int n , index;
[Code] ....
However , after I key in my characters for the string , the program does not prompt me to input a character to look for, it just prints it out and returns some funny number. But the program works just fine is I move this portion to the top :
printf("Enter alphabet to find: ");
scanf("%c",&s);

C# :: Block Program From Seeing Process Tree
Dec 7, 2011I have a program that I can only run one instance of. When I try to start it a second time, it doesn't do anything. I would like to create a script that loads the program in a way that I can run multiple instances. Since I assume the program checks the process tree on startup to see if an other instance is already running, I figure disabling access to the process tree could do the trick.

C++ :: How To Skip A Block Of Commands When User Interrupts

cout<<"E";timedelay(1);
cout<<"L";timedelay(1);
cout<<"L";timedelay(1);
cout<<"O";timedelay(1); //timedelay(int a) is a function which gives a delay of 'a' seconds.

C/C++ :: Boost Dynamic Bitset Block Size
Mar 12, 2012I am designing an application in which I need to deal with many different variables in which different sequences of bits are stored. I have very strict memory requirements so I decided to use the boost::dynamic_bitset data type which works very well in my scenario as I need to dynamically allocate/deallocate/resize the variables.
The only problem is that I am not able to change the size of the blocks in which the dynamic_bitsets are stored.
I mean, even if I specify the blocks should be "unsigned char", I always obtain 32 bytes allocation by sizeof function, even if the variable is empty.

C++ :: Point / Line And Block - How To Design Data Structure
Mar 27, 2014Suppose, I have point_c, line_c and block_c three classes:
class point_c {
public:
double x, y;
};
class line_c {
public:
vector<point_c> Pt;
[Code] ....
As you can see, lines are composed of many points, and blocks are composed of lines and points. And I defined some member functions, so that I can add points or lines as required by line and block.
But, here comes the problem, if I use line.insertPoints(), or block.insertPoints(), the points will be stored in line or block. That is not what I want.
I want have a single place to store all points, a single place to store all lines, and a single place to store all blocks.
Then I guess I need some global variables
vector<point_c> Pt;
vector<line_c> Ln;
vector<block_c> Bk;
And I should change the classes into:
class point_c {
public:
double x, y;
};
class line_c {
public:
vector<size_t> PtIndex;
[Code] .....
in this way, the member functions will create the real entities into the global vector and set an index pointing to that entity. But this approach just make me feel it is not OOP anymore. when people using these classes, they got be careful about the global variables.
