I don't know why since I've assigned a value like that to a variable of that same type before. Unless I had garbage data somewhere and didn't realize it.
Code:
#include <stdio.h>
#include <stdlib.h>
void f(char letter,char *str) {
int i=0;
char CAPletter = 'A' + letter - 'a';

OUTPUT:

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 get a error "Not all code paths return a value" what is the reason i get this error
public String giveHint() {
int hintPossible, x, y, val;
_game.hint(out hintPossible, out x, out y, out val);
if (hintPossible == 1)
return "x: " + x + "y: " + y + "val: " + val;
}
giveHint() has a red underline and it says not all code path returns a value ....
Here's my code
bitIndex = 5;
Code:
bool getBS(PBitSet _this, int bitIndex) {
if(_this->bits & (1 >> bitIndex))
return true;
else
return false;}
I want this code to return the value of the bit at position bitIndex. It can be either false or true. The problem is, that it always returns false, even thought I enter 16 as my number, so the 5th bit should be true.
0000|0000 = 0
0001|0000 = 16

I am trying to read data from more than one file at once. The files are different types e.g. one is a text file one is an xml file like so, StudentInformation.txt, CollegeInformation.xml. The files are all stored in one place, in this case on the D drive of a local computer. I am trying to locate any files in the D drive with a file extension of .txt or of .xml (there may be more than two of these files in the future, so I'm trying to allow for that). Then I want to open all of these files, extract the information and output all the information in one display window. I want all the information from these two or more files to be displayed together in the display window.
Here is the code so far. It is throwing up errors.
//Load from txt files

IEnumerable<string> fileContents = Directory.EnumerateFiles("D:\", "*.*", SearchOption.TopDirectoryOnly)

.Select(file => ParseFile(file));}

My function has the following prototype:
std::vector<double> calculate_mag_response(double start_freq, double end_freq,
int N, std::vector<double> num, std::vector<double> den
The function should return a vector size N of magnitude responses in decibels of the transfer function defined by numerator and denominator vectors num and den. To adequately test, you should drive this with more transfer functions.
#include <vector>

#include <cstdlib>
#include <ifstream>

I have not yet finished designing the interface for a couple of the operations, but right now i am hung up on trying to return to the beginning. I believe it is because the j was defined inside do and isn't carried out of the do statement for while.
I have been asked to create a program that accesses an inventory file done in excel, look for a alpha-numeric code, which will be inputed by the user, and return to the user informations related to the position of that code, and informations related to the header of the column in which the code resides.
An example of the function I need the program to perform would be:
User inputs: 1429-R1
And the program returns: Marco's 6A, 8/21/2014, 3/7/2014.
using the following example of file:
Marco's 6A

How to make a source code into a functional program that a user can open and use without coming across the source code and building or running it.
View 1 Replies View RelatedI have a Third Party MS-DOS program, RUN.EXE
RUN.EXE do the following:
1. Read FILE.INP as input file and run its code execution.
2. When finish, RUN.EXE will produce FILE.OUT as the output of its code execution.
3. However, if calculation made in the code execution come to unsatisfied condition, RUN.EXE will terminate without producing FILE.OUT or partially produce FILE.OUT.
I want to write a program using MFC which I can set a several input case. The program should be able to:
1. Call RUN.EXE.
2. Wait for RUN.EXE to exit.
3. Continue with other code.
I can't modified RUN.EXE. I can't have RUN.EXE callback my program to let know it finish its work.
Are there any functions to call RUN.EXE, a MS-DOS program? Are there any way for the program to check if RUN.EXE finish its work and exited?
