Every time screen2() runs it always outputs "Numbers entered were 0 and 0". I want the numbers that were entered in by the user in screen1() to be displayed.
I have this code where I am trying to retrieve the contents of the variable dev1 and dev2. for some reason when i compile and run I am getting 0 and 0.
I'm truing to write a function that gets an array of arrays, and returns an array. I placed the code I'm using below, but I'm getting all kinds of errors. How is the right way to do this?
Now the book says to take the following program and add a member function to the CarType class which prints the values of all of its data members. Add two more data members which are relevant for cars. Add the use of these data members to the program (to the assignment statements for MyCar, to the operator prompt and input inside the getYourCar function, and to the print function you have created).
Here is my code. Whenever I run it, it takes my assigned variables in MyCar and prints those instead of the one which the user is inputting.
#include <iostream> #include <iomanip> #include <string> using namespace std; using namespace std; struct CarType { string maker;
I have a project for class where I have to create a structure and get user input for 3 structure variable arrays of 10. I am trying to figure out how I can use the same function to fill my different section of variables.
My Structure is an employee file of ID number, name, hours, payrate, and then gross pay. I have to create a function for each input function. I am confused on how to pass the structure variable so that I do not have to write 3 functions for each input. I would like to be able to get all the info for the first structure variable and then recall the same 5 functions for the next before moving along. I hope that I have been able to make this clear. Here is my code:
It is said that variables in a function cannot be changed by another function. Only by using pointers can variable values be changed. I am writing some functions to try to prove this theory, but I can't get it right.
Code:
#include <stdio.h> #include <stdlib.h> int main(void){ int x = 10; printf("default x value is %d ",x);
[Code] ......
Code:
#include <stdio.h> void try1(int x){ printf("x in try1 is %d ", x); x++; printf("x in try1 after ++ is %d
I need making my main function to run while not having any if or for statements. It can only declare variables and functions. Since my main function has command line arguments, how to so.
// This program counts all the words in a given file.
There are, or course, better ways to do this, but I need to stick to some rules:
(1) Use only pointer variables and not arrays or structs. (2) Use the three functions shown--regardless of easier methods.
The program should ask for some input, operate on those numbers, and then display the results. I know I am confused over these things:
(1) All that syntax using '*' and '&' or neither. (2) How to use the char type correctly. (3) How to use a char type input as an operator (a + b). (4) How to use the pointer of the operator variable (+,-,*,/) in an actual equation.
So I need to make a main function have no if/for/etc. statements so I need to move it to another function and call it in main. The problem is that it's a command line argument function so I'm confused on how it works. Here's an example:
Code:
#include <stdio.h> int main(int argc, char* argv[]) { printf("The program name %s", argv[0]); if (argc == 2) { printf("Argument supplied is %s", argv[1]); } else if (argc > 2) { printf("Too many arguments");} else { printf("One argument");} }
How can i make this into two functions with main only declaring variables and calling other functions?
I know how to make a namespace i just want to know why someone would. because it just seems like a way to show a bunch of variables and functions into a compact area.
Code: int a[6]={1,3,5,8,10,12}; int b[3]={3,5,9}; int c[6]={0}; if a is equal to ANY of the data in b, then c= a*2 if a isn't equal to any of the data in b, then c=a.
Here is the answer I want
Code: c[6]={1,6,10,8,10,12}
I tried using two for loop, but it isn't correct.....
Code: int a[6]={1,3,5,8,10,12}; int b[3]={3,5,9}; int c[6]={0};
and get an Iterator to the beginning of the match by
matches->at(i)->begin()
How can I get the relative position of the match within the entire target string (i.e. "Unseen University", where, in this case, the positions should be 0 and 7)??
I am using the (fairly) new STL implementation, which I just became aware of, of regexes. Seems to be an implementation of boost::regex Anyway, I have code, which I would like to use to get ALL matches within a string.
This program is supposed to compare 2 strings and print out a 1 if the characters match and a 0 if they dont. It compiles but doesnt give me the correct output.
Code: #include <stdio.h> #include <string.h> void func(); int main () { func(); return 0;
I am trying to correlate the student's highest score with that student's ID. The old code is in blue and the new code is in green which includes a sort. The particular information in question is in red.
Ide1
Code: #include <stdio.h> int main(void) { /*Set up two arrays to include up to 50 elements each.*/ int st_numval_id[50] = {0}, st_val_tstscr[50]= {0}, i = 0, j = 0, temp;
[Code] .....
Enter the student's id and test score:
/*After the following input, then enter 0 to end the input*/
Student ID Test Score Letter Grade ------------ ----------- -------------- 1653 77 C 1945 72 C 1020 50 F 1955 92 A 1900 81 B
ABOVE AVERAGE STUDENTS
Ave Test Score Students Above Ave Number of: A's B's C's D's F's ----------- ---------- --------- --- --- --- --- --- 62.00 4 1 1 2 0 1
THE STUDENT WITH THE HIGHEST TEST SCORE
Student ID Test Score Letter Grade --------- ---------- ------------ 1900 0 F
'Write a program to match the user input string with the contents of text files and give the result as to which files contain the input string. This has to be done by using finite automaton.' (Any language can be used) So basically, the user will input a string (in the command line or a gui) and "we must pass the text files to the DFA" (I'm double quoting this because it's precisely what my professor told) and then display those files which contain the string. The string can be hard-coded, ie,the user will get the output file that contains a specific string. ex: 'hello'. The problem is, I have never done any program on DFA so I'm at a loss. how to write the program. Should I read the files first and then use some 'switch' or 'goto' conditions for the DFA? Below is a code I found on the internet for simulating a DFA accepting a specific string.
Code:
s: accept = false; cin >> char; if char = "m" goto m; if char = EOF goto end; goto s; m: accept = false; cin >> char; if char = "m" goto m; if char = "a" goto a; if char = EOF goto end; goto s; }
Basically I have a text file called words. I'm supposed to extract a word randomly from the file and have the user guess the word according to the definition.
I'm having trouble matching the definition to the word from the text file.
using namespace std; int main(){ int number; int count = 0; string word;
[Code] ....
Here is my text file apple#the usually round, red or yellow, edible fruit of a small tree boat#a vessel for transport by water horse#a solid-hoofed plant-eating domesticated mammal with a flowing mane and tail, used for riding television#a system for transmitting visual images and sound that are reproduced on screens soup#a liquid dish, typically made by boiling meat, fish, or vegetables, etc. bottle#a container, typically made of glass or plastic and with a narrow neck barber#a person who cuts hair toast#sliced bread browned on both sides by exposure to radiant heat radar#a system for detecting the presence, direction, distance, and speed of aircraft, ships, and other objects red#of a color at the end of the spectrum next to orange and opposite violet
