I run the program with gdb , i searched but find nothing about how i could run gdb , that shows what line of code is running constantly (i rather it also shows value of the variable on each line if it's possible ) without stopping (i mean i don't want to enter "step" every time , i just need to run the program with debugger and shows line of the code is running (without need to enter step each time by myself)is it possible? if yes , what command is needed to start gdb for this purpose?
P.S: for this purpose if i have to set breakpint i will. but even i rather not set breakpoint , i rather gdb while running the program shows what line is now executing (rather with the value of variabels).
I'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);
So I'm making setTimeout and setInterval functions.
I have this remember function (that is part of Timing class) which takes a function pointer and a void pointer, which are remembered in that object.
Another (timing) function of that object is called in every loop of the program and when specific time passes that function calls the remembered function whit the remembered void pointer as argument.
The problem is that the functions that need to be called require unknown multiple parameters, so what I need to do is make a new class that will store the needed arguments. I make the function that needs to be called and that storage object and pass pointers to them to my remember function, when the remembered function is called it stores the data from storage object in new variables and dose it's thing.
Okay, so I think I have just passed the intermediate line in my skill of c++ and my question is how do I make a program that opens unknown files extensions. for example like .plr. Because I see a bunch of files for game modifications like that, that was a good reason I started c++ too.
I try to find charecter position but evey time i run my program it give me 0 position why ? Why in my getChar function give me warning statement with no effect i can not understand this warning where is my mistake.
Code: void getChar(const char* str){ int lenStr = strlen(str); int i = 0; int posCharecter = 0; printf(" %s has %d charecters length ",str,lenStr);
I'm trying to create a program that allows the user to enter an unknown number of income and expense amounts. The program has to us see a while loop and display the income total, expense total, and total profit or loss. I've got it really close, but I'm doing the loop wrong. It counts the sentinel value (-1) towards the total, instead of just ending like it is supposed to.
#include <iostream> using namespace std; int main() { //declare variables double incomeInput; double expenseInput; double incomeTotal=0; double expenseTotal=0;
Code: #include <stdio.h> int main(){ double nc; for (nc = 0; getchar() != EOF; ++nc) ; printf("%.0f ", nc); }
It works well and I am using ctrl-D as my EOF. Now I understand that C is not really a language for dealing with text, which is why I am learning it more in depth, my degree was in robotics, and I think C is definitely the best place to be for me. So this may just be a quirk, but if I type more than 10 characters, I get the right answer from the program, however, if I type less than 10, for the sake of argument I type Hello and then return, if I at that point do ctrl-D, I get the answer 6D?
The 6 is right 5 letters and a return character, but what is the D?
I wrote one application using STL API's [vector,map,make_pair,pair]. Application is working fine in Windows 2008 server.
Same application failed in Windows Server 2012 R2 and the failure is randomly occurred.[once in 10 iteration] I suspect some of my PC update is the root cause for this random failure.
I would like to know which is latest STL version for Windows 2012 R2 server. Is there any latest patch/update released by Microsoft?
Does it good idea to use Boost lib for the same? Which is the Boost lib version for Windows Server 2012 R2.
There is no compilation issue on Server 2008/Server 2012 R2 server.
I am looking for a function or any example that shows elapsed time in seconds and minutes. I didn't find any solution for both OS Win and Linux. I am looking for example that works for both - win and linux.
I try to use "rand" to create 100 string, I'm happy I succeed, but next step i wanna know how to count each number of letters and the frequency it shows.
Here is the code:
#include <stdlib.h> #include <string.h> #include <time.h> #include <iostream> // using namespace std; int main() { const char *c = "abcdefghijklmnopqrstuvwxyz";
Ok, so I am writing this program with 10 different functions, and one of those functions needs to count how many times 0 appears in a text file. I've done this before, but I am so stumped right now. Should I get the numbers from the 2d array I have, or should I just use the text file here? Here is what I have right now:
int toursMissed(int scores[][COLS]){ int counter; for(counter=0;counter<=96;counter++){ if(scores==0){ counter++; return counter; } }
Program should continually have user enter a positive integer, and quits on zero entered. This entered number represents the total number of seconds and after each number is entered a function is called that displays the time in hours, minutes and seconds. Sample output is as follows:
Enter Total Seconds --> 3605 1:00:05
The function needs only one value parameter and should return nothing back to main. If the minutes or seconds are a one digit number then make sure to display a leading zero as the example above shows.
Here is my program. my question is how do i make the numbers appear like this? 1:00:05
#include <iostream> #include <iomanip> using namespace std;
Double values are stored in text file. 23.5 36.8 34.2 ... My teacher told me to read them character by character and then make words, like i have to read "2" "3" "." "5" and now have to make it or treat it as word and then using atoi(). I have to convert it into double. but i dont know how to do this....
