I made this function to check in string is alpha only or alphanumeric but always give me alfa way ?
Code:
int checkIfStringisAlfa(const char str[]){
int lenStr = getStringLength(str);
int i = 0;
int ret;
for(i = 0; i < lenStr; i++){
if(str[i] >= 'a' && str[i] <= 'z' || str[i] >= 'A' && str[i] <= 'Z'){
//printf(" alfa
[Code] .....
my program only checks the first character of the string.. D:
View 8 Replies View RelatedI'm trying to check to see if a string from standard input is alphanumeric or not. I feel as though there may be a function for this but...
Code:
for(test_pass = i; test_pass < i; i++){
if(test_pass[i] == ('1', '2', '3', '4', '5', '6', '7', '8', '9', '0'))
printf("Your password is alphanumeric!
");
}
The compiler wasn't too happy with this.
I am unable to check if the character in the 2D array is alpha
here is my code
#include<iostream>
#include<cctype>
#include<cassert>
#include<cstring>
const int maxChar = 20 ;
using namespace std ;
int main() {
int count = 0 ;
char d[2][20] = { "hi" , "di" } ;

I want to create 2 functions to (1) convert a passed string into proper case (capitalize the first alpha character of a string and every alpha character that follows a non-alpha character); (2) sort the array of names (after it has been converted to proper case).
I tried these two:
console.writeline (lower.toUpper());
void bubblesort (string array[],int length);
but I don't know if they are good.
I found a targa loader that works great and implemented it in my code.
But for some reason, the alpha region of my texture , just won't be alpha when I load the Texture in my code.
If I make a texture that is a full purple colored rectangle, and carve out the central part with an alpha zone, in-game the quad is all full purple, instead of having the central part being transparent.
I tried the following code too, and it doesn't work, I don't understand
//NPC
glEnable(GL_BLEND);// Enable Blending
NPC00->Draw();
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);// Set The Blending To A Nice 50/50 Mode
glDisable(GL_BLEND);// Disable Blending
Draw Function, basically draws a Quad and applies the texture to it.
I'm just trying to get textures with alpha to work, I usually work with targas, so thats why I got a targa loader.
The output should also give a file which doesnt consits alphanumeric. I tried this
while( ( ch = fgetc(fp) ) != EOF ){
if(isalpha(ch)||ch==' ')
Is this correct.than how to complete it.

View 5 Replies View RelatedWrite a program that reads alphanumeric characters from the keyboard, and computes the average ascii value of the alpha numeric characters, the average alphabetical character, the average numeric character and the average uppercase character. Outputting each, you program should terminate reading once it read a non-alphanumeric character.
Here's what i have so far.
Code:
#include <stdio.h>

int main(void) {
int value = 'a';
int digit_loop = 0;
int alpha_loop = 0;
int upper_loop = 0;

So I've been tasked with creating a program that checks to see whether or not a string is a palindrome. It has to remove whitespace, punctuation, and capitalization for obvious reasons. Getting some errors which I'm not sure how to correct.
On an unrelated note, while programming in the console, my cursor has turned into a gray box and replaces characters when typing, instead of pushing them forward, etc. How do I return it to normal?
#include <iostream>
#include <string>
#include <iomanip>
using namespace std;
bool isPalin(string& palin);
string cleanUp(string& palin);

i m learning c programming and i m stuck with this program for some reason.Write a program that converts alphanumeric phone number into numeric form:
O/P:
Enter phone number: CALLAT 2255288
here is the code i have written:
/** compilers shows no error **/
and O/P I get is
Enter phone number: CALLAT
/**blank space***/
Code:
#include<stdio.h>
int main(void)
{
char ch;
printf("Enter phone number:");
ch=getchar();

Ii made one string variable and called it email_confirm. I used cin to get the users email but i don't know to check if the email is real.(without being connected to the internet).
For example,in PHP you can use ereg() or eregi() to see if the email is real, I mean you can see how many characters the email_confirm is made off or how many characters is used after the @ or . is used. is there any functions for this?
I want to change the alpha of a sprite without changing any other colours
View 4 Replies View RelatedI want to use a new color for BaseColor in iTextSharp.
I can easily set a new color using RGB values from 0 to 255.
However, if I want to adjust the alpha value (and I know alpha ranges from 0 to 1), I can't make the alpha 0.5 because it's not an integer in the definition of BaseColor.
public BaseColor(int red, int green, int blue, int alpha);
So I can set my BaseColor like below:
static BaseColor newColor = new BaseColor(192, 192, 192);
but I can't use a non-int value for alpha. How can I easily convert double alpha values to integer values? What would be the range for alpha in int values and how do I, e.g., set the alpha value to 0.5 in int values?
EDIT: btw, I found online something like this: int alpha = (pixel >> 24). I don't understand why 24 and how can I break that into chunks I understand?
I'm fairly new to C++ and programming in general and I'm trying to get a program to check the parameters of a binary string before converting that string to dec values. I have the user input 'num' line 39 - 42, but I want to reuse that same value in the 'void bin_to_dec()' function. Is there anyway I can use the same variable between void functions?

How i could go about extracting and checking if the very first character in my string array is an alphabet
View 2 Replies View RelatedI'm trying to write a short program that takes the input from a user and trims any leading/trailing white space, and then checks how many words are in the string. Problem is, I'm only allowed to use stdio.h and stdlib.h. How can I accomplish this? Also, how would I check if any of the characters which were entered aren't either a number, letter, or '-'?
View 3 Replies View RelatedI am looking for a way to sort a string just by the alpha characters, not by the ASCII table. Therefore
string sort(string name) {
sort(name.begin(), name.end());

How to stalk a random alpha letter in order in a minimum possible way.. and write the cases which the container can be stalked.
for example.. ACMICPC can be a store in three stalks.
ACC
M -----------> three stalks

Another example... CBACBACBACBACBA can have three stalks

I'm using SDL to try to create a Run and Shoot game. But I do not know how to check if a key is down while the user is HOLDING it.
I do know how to check if a key was pressed.
I have tried with the "event.key.keysym.sym" and "Uint8 *keystate = GetKeyState(NULL)" both worked to check if a key was down but I thought that the GetKeyState(); Function would even check when a key where HELD down
I want my player to move while holding down left or right arrow. So I did something like:
Code:
Uint8 *keystate = GetKeyState(NULL);
if (keystate[SDLK_RIGHT]) {
apply_surface(x++, y, player, screen);
}
How to check if a key is held down?
I am writing a console program for a class. I have satisfied the assignment, but I want to clear up what is mostly a cosmetic problem. The program prints a form to the console and places the cursor at a location on the form where the user inputs data. The problem occurs when the user presses the enter key without entering data. The cursor goes to the beginning of the next line. If the user enters data after this, the program functions correctly. I want to know how I can reposition the cursor if the user enters no data.
This is the code that reads one of the values:
Code:
void getHousing(HANDLE screen, MonthlyBudget &inputBudget) {
placeCursor(screen, HOUSING_ROW, ACTUAL_COL);
cin >> inputBudget.housing;
while (!validateEntry(screen, inputBudget.housing)) {
placeCursor(screen, HOUSING_ROW, ACTUAL_COL);
cout << SEVEN_SPACES << endl;
placeCursor(screen, HOUSING_ROW, ACTUAL_COL);
cin >> inputBudget.housing;
}
}
validateEntry checks that the entered value is >= 0 SEVEN_SPACES is a string of seven spaces to cover up the previous entry.
I'm currently trying to write a while loop that checks if the text file has read all the contents inside. I've tried using
while(!in.eof())
but as usual it executes my loop an extra iteration, printing my last output twice. I am reading my data in from a method inside a class, so I cannot use getline as my while test to check if the file has read input or not. Is there any way to force my loop to check if the end of file has been read before the eof() test is executed?
