C :: How To Take String Of Numbers And Turn It Into Array Of Integers

Mar 2, 2014

I know strings are essentially just arrays of characters, so what would be the easiest way to take each individual digit and put it into a separate space in an array?

ex.) *str = "90210"

array[0] = 9
array[1] = 0
array[2] = 2
array[3] = 1
array[4] = 0

All my attempts at achieving this just result in an array full of garbage numbers. What I've done is

Code:
int *array;
array = malloc(sizeof(int)*(strlen(str));
for(i=0; i<strlen(str); i++) {
array[i] = str[i]
}

also, I should mention that the string will be defined in main, and its converted into an array in a separate function.

C++ :: Turn Based Game Turn Order?

Feb 14, 2013

How would one cycle through a turn order in a turn-based game? I was thinking an array of every creature (including the player) and have a pointer to the array++ after the turn, but I couldn't put all the objects into an array.

C++ :: How To Turn A String Word Into Letters

Dec 9, 2013

I'm having trouble trying to turn a word into letters. I've seen other posts but they deal with a sentence and it only outputs the words only. What I want to know is how do they take a word (Ex: "word") and break it into individual letters, where I want to store them in a vector of string?

If it's not too much trouble, I would prefer without using pointers or "std:: " marks, since I am trying to avoid pointers and I'm using "using namespace std" all the time.

Ex:

In the example "word", it should output into:

"w"
"o"
"r"
"d"

and I will push them back into a vector of string where each vector element contains a letter.

For Example, it the entered string is: 0324152397 I want it to get stored in an array like-[0] [3] ...[7]. Secondly the string entered may be of any length that is defined only at run time. So, I also need to calculate string length. How could I do that.

Feb 4, 2014

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)

C++ :: Turn Binary File Data Into Unsigned Character Array For Inclusion In Executable

Jul 10, 2013

C/C++ :: Converting 8-byte Integer To String Based Integer

Oct 15, 2014

Complete the function myitohex so that its converts 8-byte integer to string based hexadecimals.

Ex: printf("0x%s",myitohex(64,hex)); should printout "0x40" on the screen
char *myitohex(uint8_t i, char *result){
???
return result;
}

I wrote:

#include <stdio.h>
#include <stdint.h>
char *myitohex(uint8_t i, char *result){
*result = i + '0';

[Code] ....

0xp gets printed out which is wrong. I think *result = i + '0'; is wrong. What changes should i do on this row ?

C :: Assign Integer Value To Unsigned Char Array But It Is Not Storing Integer Values

Oct 25, 2013

I am trying to assign the integer value to unsigned char array. But it is not storing the integer values. It prints the ascii values. Here the code snippet

Code: uchar uc[100];
for(i=0;i<100;i++)
{
uc[i] = i;
}

The values which are stored in uc[] is ascii values.I need the integer values to be stored in uc[]. I tried to do it with sprintf. but the output is not as expected. if I print the uc[i] it should diplay the value as 0,1,2....99.

C/C++ :: Including All Repetitions For One Turn

Feb 22, 2015

I am trying to include all repetitions for just one turn but I keep getting

00.0 but I want (the one in red)
170.3 0 0.3
180.0 17 0.0
190.3 18 0.0
200.3 19 0.3
210.0 20 0.3
220.0 21 0.0
22 0.0

so basically I call a function that represents just one turn of getting a random number, and then when the player decides he wants to get a random number that is at least 17 and wants to repeat this 3x I have to print out this chart that shows the chances of the player rolling the numbers between 17-22 [how many times does he get 0,17,18,19,20,21,22] this is what I have

cout << "your score: " << (' ') << "chances for that score:" << endl;
/* score is the player's total score for the one turn */
int score = 0;
int score0 = 0; // 0

[Code]....

Oct 2, 2013

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;
