I'm having a problem converting part of a string to an integer.I used strtok to seperate my string and I have also a function for atoi but how to apply it to my strtok function.What i need is to change the char *years to an int.Have a look of what I got:
Code: int main() { char sentence[]="trade_#_2009_#_invest_#_DEALING"; char *word=strtok(sentence, "_#_"); char *year=strtok(NULL, "_#_");; // assigning NULL for previousely where it left off char *definition=strtok(NULL,"_#_"); char *synonyms=strtok(NULL,"_#_");
I have been trying to write a function which can convert a number from an unsigned long integer to a readable ASCII character string. this is what I have come up with, but I am receiving some very strange characters in return. Could the problem be that I am telling a char to = an unsigned long int, (cString[i] = product[i])?
void convertToString(unsigned long con) { unsigned long product[10]; char cString[10]; const unsigned long begConvert = 10 ^ 10;
I'm just learning and C. Here is a code snippit from a program that will compile. It's function is to validate credit card numbers. I have an error I can't find though. the last print statement shows the conversion in reverse string (as integers). Here is the code:
int main (void) { char cn[17]; char *cardtype; int n0,n1,n2,n3,n4,n5,n6,n7,n8,n9,n10,n11,n12,n13,n14, n15; int s1,s2,s3,s4,s5,s6,s7,s8; int oddsum; int sum; int total; int validate; }
// prompts the user for a non-negative numbers (>= 0) // reads in the a number and checks // keeps re-prompting user if the input is invalid (negative)
[Code].....
How do I go about Populating the elements in the array created, I keep getting a compiler error on this vArr[i] = tmp_stream.str.at(i);
My intent was to convert the string variable for the year to an integer data type. The code compiles but now cannot run on my system. I'm not sure what's going as to what the program is displaying.
Objective: Prompt the user for two years. Print all Comedy movies that were released between those two years.
#include <iostream> #include <cstdlib> #include <string> #include <fstream> #include <cctype> using namespace std; struct Movie { string name;
I have to implant a code to convert any integer to its 2'complement. I have already finished the first and the second part, which was to convert the integer to its binary representation, then to invert each digit in the binary representation. The third part is to add 1 to the binary representation.
// the last step is to add 1 to the binary number int carryIn=0; int carryOut; for(itr= bainaryList.begin(); itr!= bainaryList.end(); itr++) { //start comparing the possibilities of the values in both lists if (((*itr)==0) && (carryIn== 0))
I'm trying to read in two instances of date and time (from user input) into a string value (MM/DD/YY hh:mm). I need to be able to calculate the difference between the two in order to return how much time has elapsed from the first date/time to the second date/time.
What would be the most efficient way to go about obtaining said results?
I was thinking I need to convert each year, month, day, hour, and minutes into its own integer variable, after researching immensely online I'm still not sure how to convert from a string of characters to an integer.
I am trying to read an array values from Tmin.txt file. I take array size from user viz. number of raw & column and then, read the following data from Tmin.txt file which look like this:
20 40 20 25 30
20 30 40 20 25
20 40 20 25 30
20 30 40 20 25
30 40 40 30 40
I am using getline, and then converting it to int by using atoi. But my code is not working.
Code : // reading a text file #include <iostream> #include <fstream> #include <string> using namespace std;
convert a positive integer code into its english name equivalent for digit. A valid code is of size between four (4) to six (6) digits inclusive. A zero is not allowed in the code.
example : if the input is 234056 the output is : INVALID CODE (PRESENCE OF ZERO) if the input is 23456 the output is : TWO THREE FOUR FIVE SIX if the input is 9349 the output is : NINE THREE FOUR NINE if the input is 245 the output is : INVALID CODE (3 DIGITS) if the input is 2344567 the output is : INVALID CODE (7 DIGITS)
step 1 : input code step 2 : count the number of digits in the code step 3 : if there is a zero in the code, "INVALID CODE (PRESENCE OF ZERO)" go to step 4 step 4 : if number of digits is mode or equal than 4 and less or equal than 6, go to step 5 else display the following message "INVALID CODE (<number of digits> DIGITS) step 5 : call a function called digit_name to convert each digit into its equivalent english name. display the result step 6 : print the digits in reverse order eg; if input is 13453, reverse order is 35431
i was trying to solve a problem in SPOJ and what i wanted to do is to accept an input number from the user and to convert it into a array of integer.
Code:
#include<stdio.h> int * toarray(int *num); int main(void) { int testCases; }
[code]....
But whenever i try to print the array in the main function i get only two value and the rest address
Code:
1//number of testCases 23456 //input number 6 2293452 4 2293700 1974439125
Process returned 0 (0x0) execution time : 4.152 s Press any key to continue. However, if i tried to print the array from within the function, it prints the numbers just fine.
print the array elements from the main program, so that i would be able to go on with the rest of it
Ok, so I'm writing this code and when I build it keeps saying cannot implicitely convert type int to string even though I declared my variables as string. Why is it giving me this error?
private static string Repair() { string result=""; string beep; string spin; Console.WriteLine("Does your computer beep on startup?:(y,n)");
these function do the same of the sprintf() function. but instead we use a variable for add the result, i want to return the result. when i use it:
string f; f=ToString("hello world"); gives me several errors: "error: crosses initialization of 'std::string f'" "error: jump to case label [-fpermissive]"
I am using Visual Studio 2008. I just wonder if there are any library function in Windows SDK or MFC, or from third-parties, that can convert a UTF-8 string into Windows Unicode string(used in CString object).
Can MultiByteToWideChar or ATL String conversion macro like A2W to the conversion?
i'm having difficulty with a problem, i need to add two big numbers suchas 54646774456776 and another one 445556777554 and it would print the result. how can i approach this problem without the use of arrays?
Write a c++program that asks the user to enter positive integer numbers without points between 0 and 999. Then check the amount and print in words. You need to use dynamic ragged arrays..
This is my solution but I'm not sure if this is the right way for dynamic ragged array???:
I'm working on a program and I need to convert big numbers to radix 64. I would like to shorter them whit conversion that's why I choosed base 64. I have two problems:
1. The conversion works only for not so big numbers. Untill about 2^32. I would like to convert bigger numbers. Is there any solution? (I thought on GMP/MPIR library, but I can't managed it.)
2. The conversion back to decimal base doesn't works, because I use 'strtoul()' which doesn't support bigger bases like 36.
