Hmm, interesting case. You want to be able to loop with, let’s just call it hypothetically the largest possible number, and thus wrap-around rather than ever having the comparison return false. Something like this might do the trick: char arr[SIZE_MAX]; size_t i = 0; do { /* whatever you wanna do here */ ++i; } … Read more
The problem is near break statement, Your break statement is being executed without executing a++;. Here is the correct code. #include<stdio.h> #include<string.h> void main() { int a=0, copy[10]={0},len,i; char string[10]; clrscr(); puts(“enter a number string”); gets(string); len=strlen(string); while(a<len) { for(i=48;i<=57;i++) { if(string[a]==i) { copy[a]=i-48; a++; break; } } } for(i=0;i<len;i++) printf(“%d”,copy[i]); getch(); } solved this … Read more
No, Convert.ToInt32(text) will just try to parse your text to an int, like: Convert.ToInt32(“032”) will return 32 as int but Convert.ToInt32(“Brian”) will throw an exception. I assume that you want to have some kind of hashing, when you say “different words to the same int”. Try GetHashCode(). It will return the same value if you … Read more
There’s several problems with your code. First, the swap function doesn’t work. You’re swapping the values of the pointers that are local variables inside the function, you’re not swapping the array elements they point to. You need to indirect through pointers to get the values. int temp1 = *a; *a = *b; *b = temp1; … Read more
Just to start with : In main: int n, a, b; // a & b are not initialized . scanf(“%d”,&n); // Think what is the use of n here. . printf(“%d”,inner_product(&a,&b,n)); /* You passed address of a and b, this is OK but the value they * store is indeterminate as per the standard */ … Read more
The most efficient method is to read blocks or chunks of data into a buffer than scan the buffer. The I/O has an overhead cost and the more data you can fetch per request, the better. Searching in memory is always faster than reading one character at a time from the input. Be aware of … Read more
Signed overflow is undefined. Unsigned overflow wraps. Implementing signed wraparound arithmetic is mostly a matter of doing everything in unsigned math. There are a few things to be careful about, though: unsigned short and unsigned char arithmetic works by converting the operands to either int or unsigned int first. Usually int, unless you’re on a … Read more
yourString = yourString.Replace(“,”, System.Environment.NewLine); Demo here https://dotnetfiddle.net/M2lBKS solved C# string replace “,” with a linebreak (Enter) [closed]
You are expecting the cast from int to unsigned int to simply change the sign of a negative value while maintaining its magnitude. But that isn’t how it works in C or C++. when it comes to overflow, unsigned integers follow modular arithmetic, meaning that assigning or initializing from negatives values such as -1 or … Read more
Use google. In C++ you must define a type of variable. Look for a C++ tutorial, there are many of them. Use google. 1 solved C++ code is wrong
I’m not sure what is your question, but as @crashmstr commented .. it seems you don’t need an Enum but you just need a class to hold these properties Any way you can use this BUT IT’S NOT A GOOD PRACTICE and I don’t know what do you want the setter to do public string … Read more
I need to get process name from process id in windows to find process names associated with a logged event. If you are getting the Process ID from a log, it will only be valid if the original process is still running. Otherwise, the ID is no longer valid for that process name. If the … Read more
It is completely up to the implementation. For example, const data on bare metal ARM uCs is stored in the FLASH memory. You can write to there but it will have no effect at all. Hosted systems will behave differently depending on the OS, its version and hardware. How can I overwrite a const block … Read more
int a[5] a is an array of 5 int. int (*a)[5] a is a pointer to an array of 5 int. int a[5][4] a is an array of 5 array of 4 int. int *a[5] a is an array of 5 int pointers. 6 solved What’s the difference between “int a[5]” and int (*a)[5], int … Read more
You can use an extension method like this public static class StringExtensions { private static char[] _alphabet; static StringExtensions() { _alphabet = “abcdefghijklmnopqrstuvwxyz”.ToCharArray(); } public static bool ContainsAlphabet(this string input) { return !_alphabet .Except(new HashSet<char>(input)) .Any(); } } “asdasd”.ContainsAlphabet(); //false “abcdeffffghijklmnopqrstuvwxyzzz”.ContainsAlphabet(); //true 0 solved Check if the string contains all the characters from a to … Read more
