C :: Printf Ints That Are Modified In Another Function?
Feb 13, 2013
I have gotten it to record the date and I can printf it either on the same function, or in the main(). However, one of the requirements I must adhere to is to printf the statement in a brand new function, but when I do that, it just doesn't work. Heres what I mean:
Code:
#include <stdio.h>
#define TICKER "LRCX"
#define INVESTMENT_AMOUNT "10,000.00"
//Prototypes
int getdate(int* month1,int* day1,int* year1,int* month2,int* day2,int* year2);
float getprice(float* BPrice, float* SPrice);
void printdate(int month1, int day1, int year1);
}
Variably modified types are subject to certain restrictions , just as variable-length arrays are. The most important restriction is that the declaration of a variably modified type must be inside the body of a function or in a function prototype.
Code: void f(int m , int n) { int a[m][n] , (*p)[n]; p=a; //.... }
What does it mean? That we can't declare such a pointer as a global variable?
I am getting a string from the consle and that all works fine. I'm expecting a string of number, ie 123456.... I store that fine in my string object. I then need to take each individual number, ie 1, and put it in a vector then take the next number, ie 2, and put that in the next element in my vector.
Everything i've found and does eaither takes the entire string and stores it as an int, or takes the ascii representation of the number and stores that. How do I seperate each individual number and store them seperatly. below is a few different variations i've tried that doesn't produce my desired results.
cout<<"Please type the memory memory frames (numbers 0-9) to be used to simulate the input memory "<<endl; cout<<"Your input: "; string line=""; cin>>line; cout<<" Please wait while your input is processed and validated..."<<endl;
[code].....
the only thing i havn't tried yet is string streams and i don't necessarly like using them. Am i going to have to go that route? will that even work?
EDIT:I forgot to mention that this is being done on linux and then ported to unix.
I am trying to figure out the larger 2 out of 3 integers when i call them into a function from main program so far i have . How to write a simple function that will take 3 ints and find the sum of the higher 2?
Code:
int findsum(int a,int b,int c)// will find the highest int and return it to our main program { int max,max2;// this sets our local variable max // next we will find the larger of our first 2 variables if( a>=b)
[Code]....
How to get the second highest number and add it to max...
I'm making my way through most of this assignment that I have, but now it seems like I've run into a bit of a roadblock. The issue that I'm having is not being able to printf a series of ints that I thought I had previously defined in another function. I don't want to clog up this post with the entire code, so I'll just post one function that defined an int to give an example. I will upload the whole thing upon request however.
Code:
#include <stdio.h> #include <stdlib.h> //Prototypes int AGrade1(int* grade1); int AGrade2(int* grade2); int AGrade3(int* grade3);
[Code] .....
I've tried many many things, but I just cant figure it out. This is what it's supposed to look like.
I am trying to modify a PerformanceCounter I have created in C#. But it doesn't seem to be that it is being changed. This counter needs actualy to be a flag : 0 or 1.
I took the following code from the web. It created the collectors category along with the counters well. But the RawValue always shows 0!
I am working on Win7/64.
using System; using System.Diagnostics; using System.Runtime.InteropServices; namespace PerformanceCounterSample
How to create text file in C programming. And after some changing in that text file off the running code of C, I want to read that modified text file back in C running code. e.g
Created file may have number 1, after changing this value to 2 let say, than I want to read that 2 value which is in text file.
I have some paper work to do about a game I should be able to play with my class mates. We should be able to send and recive a struct concerning about the 'moves' of the pieces at the game. This struct is made of 4 ints, simple as that.
I had a previous paper work to do where I'd have to send ints and that was ok, but now that I have to send a struct I'm failing to do so. This is What I've tried:
//SERVER struct message{ int code; int piece; int x; int y; }send; bytes_sent=write(new_socket,&send,sizeof(message)); cout<<bytes_sent;
So far so good, I see 16 as bytes_sent's value.
On the other hand:
//CLIENT struct message{ int code; int piece; int x; int y; }recive; bytes_recvd=read(my_socket,&recive,sizeof(message)); cout<<bytes_recvd;
At first i had my int variables in global scope however i cant do the so im trying to pass my variables from my main to the void functions but cant.....
I am trying to generate some lists of permutations of ints but I can't make std::next_permutation work for me. The problem is I need to include permutations which don't use every number. For example take the array of numbers [1, 2]. I need an algo that will return:
I'm supposed to create a program that will find the min/max values of two ints, doubles, and chars, It's not completely done but here's what I have so far.
It's giving me an Error 1 error LNK2019: unresolved external symbol "public: __thiscall MinMax<int>::MinMax<int>(int,int)" (??0?$MinMax@H@@QAE@HH@Z) referenced in function _mainC:UsersDerickDesktopCiss243Week3 Assignment2Week3 Assignment2Main.objWeek3 Assignment2

I have been trying to figure this out for a text based game. Lets say your money is 500. Then you save your game, but when you start the game the starting is 50, so when you load it, you still have 500 money, I tried lots of test, and im having trouble?
The code is supposed to take either an int or a string (and their respective vectors) and insert a given int or string into the vector in ascending order. My code works properly for ints, but it's having a problem with strings.
The order I get with the strings given is
penguin banana great jungle
For some reason comparing penguin to banana/great doesn't give the expected result. The template attached only includes the function and the private vectors needed for the function.
template<class T> class orderedList { public: void insert(const T& item); private: vector<T> list; int total = 0;
I have saved the contents of an int vector to a txt file and the numerical data was converted into a c-string. Nov I need to import and read the contents back into my program but I have not been able to convert c-string numerical data back into ints.
I am working on an assignment to create a Complex number calculator. In this assignment I am to ask the user for input to the calculator. We are given a sample run output that looks like this.
Enter operand1: 3 4 operand1: (3, 4) Enter operation : + Enter operand2: 1 2 (3, 4) + (1, 2) = (4, 6)
My question is how would I take from the user: an integer followed by a space followed by another integer and convert that into two seperate accessible int values that I can save as real and imaginary values.
I am having a hard time with some of my homework, specifically regarding how to printf floats. I can't seem to print the number i want out using float, it just becomes a jumbled mess.
Thats the code I currently have, I've probably tried everything to get the number to come out, but I just cant seem to figure it out. It should look like this, but with different numbers and stock:
#include <stdio.h> struct database { int id_number; int age; float salary;
[Code] ....
When I compile, I get an error: test.c|18|error: incompatible type for argument 1 of 'printf'| note: expected 'const char *' but argument is of type 'float'|
I thought employee.salary is a float but the compiler expected 'const char'. How do I make this work?
I have the following line of the code. Now I want to save the content to a string. Is there a quick way for me to do the conversion using the same arguments/codes of printf?
I am having trouble with the printf in this function:
Code: void print_orig_array(char string_array[MAX_PEOPLE][NAME_SIZE], int ages[MAX_PEOPLE], int length) { int counter; printf("Original list"); printf("

Here is the output:
Am I missing something with the format specifier? How do I fix the 84 that gets pushed out?
