You’ve tagged this as c++ but it seems like you’re using entirely c.. So I’ll answer this as if it’s c. A segmentation fault occurs when you access memory that you don’t own. In this case you’re trying to print a character outside of the bounds of your string. (e.g. your string is len characters … Read more

Why are you writing this line largest = nvalue; ? And your if-else if commands are totally wrong. Try this code: #include <stdio.h> int main(){ int largest = 0; int no1, no2, no3; printf(“Number1: “); scanf(“%d”, &no1); printf(“Number2: “); scanf(“%d”, &no2); printf(“Number3: “); scanf(“%d”, &no3); if ((no1 > no2) && (no1>no3)){ largest=no1; } else if … Read more
You are indeed missing something basic – namely, that the output of your function doesn’t depend on answer at all. No matter what you feed in as answer, because 6 > 5 is always True, it will always return the result of that case. What you need is def greater_less_equal_5(answer): if answer > 5: return … Read more
You might want to write a number as binary (base 2), octal (base 8) hexidecimal (base 16) or as a short id (base 36) Are any advantages or disadvantages??? Generally, decimal is fine, however sometimes the number either has to be in a particular format or it makes more sense to read it as a … Read more
This will shift chars to the right, making room for insertion. void rshift( char *s ){ int n = strlen( s); s[ n + 1] = 0; while( n ){ s[ n ] = s[ n-1 ]; n–; } } int main(){ char *p = strchr(sentence , replace); if( p ) { p++; // insert … Read more

Your code doesn’t add much to your question, so I don’t really know if this is what you are looking for, but here is some code to call a function every X time (swift 3): // call MyMethod every 1 second : Timer.scheduledTimer(timeInterval: 1, target: self, selector: #selector(MyController.myMethod), userInfo: nil, repeats: true) Please search before … Read more

No, it is not necessary to replace use of Collections.synchronizedMap with ConcurrentHashMap when used by multiple threads. The Concurrent Collections section in the javadoc for package java.util.concurrent says: “Synchronized” classes can be useful when you need to prevent all access to a collection via a single lock, at the expense of poorer scalability. In other … Read more

First, you will need to push your prime numbers in the vector. At the beginning, unless you ask otherwise, the vector is empty. You can push a prime number using this snippet: // somewhere you declare your vector std::vector<unsigned long long> primes; // code computing a prime number unsigned long long prime; …. // Push … Read more

Variables and array elements are all references to objects. They are not the actual objects. To illustrate, I’ll “name” actual objects using a number scheme, e.g. #1 is the first object. Your code runs as follows: Class is initialized by the JVM, and root1, root2, and root3 are all null. Node root[]={root1,root2,root3} is executed and … Read more
