I am currently working on a c++ project that will input students and process their grades. I encountered a problem and my code stops executing after the getScores function. Im not sure what the problem is, but im guessing its something within the function and the loops.
//Name: getScores
//Description: Will get scores for student
//Parameters: None
//Return: testScore
double getScores()

I tried.
cin.get();
and
return 0;
is there a better way to keep the user info displaying without closing the console window.
Is there a way to tell the program to continue reading the next line of code within a nested IF statement?
The reason I want to do this is because the two "else" statements in the following sample (the main and the nested else) will contain the same exact code and I don't want to repeat it twice. I know I can do this by creating a function and calling it from each else statement but I was just wondering if what I'm asking is even possible without using a function.
if(1 < 2) {
// yes 1 is less than 2
if(5 > 10) {
// do something
} else {
// no, 5 in not greater than 10
// here is where I want to tell the program to continue reading the next else statement

I have this problem for an assignment, and one of the functions that I created for it is nothing fancy; just a function that'll take in a number and error-check to make sure the input is valid. However, after doing it, when the program calls that function, it skips the cin statement and ends the program, without letting the user input his number. The function in question is called getSubLength.
Code:
#include <iostream>
#include <string>
#include <iomanip>
#include <cstdlib>
using namespace std;
const string JANUARY = "January";
[code]...
As I was testing it, the program suddenly stopped giving an output. Here is the code:
#include <iostream>
using namespace std;
int main() {
cout << "Ten people ate breakfast with you this morning. Each of them " <<
"had pancakes.
Please enter how many pancakes each of the ten people " <<
"ate.
" << endl;

The while loop after int glutton does not work and seems to stop the program. I replaced the "glutton" in the cout with "testing testing" and it still did not work. However, when I commented out the loop, it appeared. Finally, it can't be what's inside the loop, because I commented that out too, and it still didn't work.
the program is of an address book. the syntax is all fine, and the initial menu of options does show up. but once you punch in the cin, the program just stops.

Just using Find in my source code to look for variables or whatever, works once or twice then just stops - Doesn't find anything even if it's there. If I restart VS it works again, but not for long.

how I can run this as a separate process from the parent program, like a child process,
and return the result back to the parent program.
this script is as follows.
if file "/Stuff/s" exists then continue to run, if file "/Stuff/t" exists, then print "started" if file "/Stuff/t" does not exists, then print "stopped"
if file "/Stuff/s" does not exist then print "quit" and then quit.
Code:
void controlxmmscheck( ) {
if( access( "/Stuff/s", F_OK ) != -1 ) {
xmmscheck
} else {

I'm having troubles with this program I made. Put it simply, it's a basic program using Queues. Whenever I try to input a value, my compiler(Dev C) suddenly stops working. The .exe file crashes and I've no way on how I can execute my program.
Code :
#include<iostream>
using namespace std;
int *queue;
int rear, front, queueSize;
void enqueue();
void dequeue();
void display();

I'm making an apllication which needs to play .wav file when user type something inside QTextEdit. I made some code but after minute or less the sound stops, so I made silly workarround. After 30 clicks I invoke sound->stop(); and then the loop start again, that works, but it's not good, can you give better solution. Here is my code:
Code:
int count = 0;
bool MainWindow::eventFilter(QObject *o, QEvent *e){
if(e->type() == QEvent::KeyPress)
{
tipka->play();
tipka->seek(0);

We have been assigned to create a program that uses multiple functions. The professor has given us code for two of the functions, one to open a file and then another one to read the files contents and output them. I have put these into my program but they will not execute. The program does run, but the functions themselves are not executing. I have practiced with other functions that contain no parameters and those run fine, but the functions she gave us have multiple parameters.
The code I have so far is below:
#include <iostream>
#include <iomanip>
#include <fstream>
#include <string>
void PrintFile (string FileName, ifstream& inFile);
int main () {
ifstream inFile;
string fileName;

Supposing that class A is the development code; and so for unit-testing purpose I create a mock for it. But I don't know how to override A's constructor such that it will not get executed in my unit-test code.

I have a function that needs to return a "uint8_t" value. However before doing the processing I need to perform a test on the argument to check if it's between expected boundaries. Although this function works it gives (a logical) warning that not always a value is returned although expected. What is the normal way for functions like these where I normally should return e.g. -1 in case the test doesn't succeed and otherwise the uint8_t (t) value?
Code:
uint8_t myFunc(int a) {
if (a >= 0 && a <= 100) {
// Perform actions
uint8_t = ...
return t;
}
}
I 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++.

View 9 Replies View RelatedI want to implement some "debugger like" tool (very limited one, just identify at running time the current stack trace, and print messages from the user) on some code that the user wrote. what I get from the user is a function name (in the beginning of it's declaration), and when the user want to print some message he uses some print macro I should implement.
My target is printing the stack call, and all the messages that the user wrote, in the right place on the running place.
By what c++ feature can know on running time that a specific function code has ended??
Its easy to push a function to some vector when it called (since I get its name from the user), but when it ends and return to the function called it...
This: "The compiler may not always be able to insert the code for a function inline (such as with recursive functions or functions for which you have obtained an address), but generally, it will work."
For a function inline why wont it work for a recursive function or a function for which you have obtained an address?
Why cant the compiler still insert the inline?
