setDateTime() accepts ints as parameters, yet you give it char array. The call should be: clock.setDataTime(2017, 3, 22, 16, 20, 4); 0 solved error: invalid conversion from ‘char*’ to ‘uint32_t
You explicitly ask the compiler to generate unoptimized code with -O0. The result is indeed rather slow as the nested loops do not get optimized away. The java compiler probably does that and removes the empty loops, a rather easy optimization. If you could require the java compiler to generate unoptimized byte code and prevent … Read more
It helps to read the documentation, that would have told you queue<int> q; … int cur = q.front(); q.pop(); solved Assign first item of queue to int [closed]
The problem is that you input too many characters for cin >> ch;. Since m == 40, you declared it as char ch[40]. This allows you to enter 39 characters (not 40 because of the trailing ‘\0’ character), but you entered much more than that, so it wrote outside the array boundary, which results in … Read more
bThere are several problems in your code. On the fourth line you have int Test = Console.ReadLine(); Console.ReadLine() does not return an int, but a string. string Test = Console.ReadLine(); The name Test is not very descriptive and also violates the convention, that local variables should start with lower-case letter. So we can further improve the line to: string input = … Read more
You can of course use <=. SELECT COUNT(value) FROM primes WHERE value >= 2 AND value <= root; solved Sql Count Query for starting from a value [closed]
Shoulbn’t be that hard to figure out but here: //instead of var use the actual type FacebookClient client = new FacebookClient(); //again use the actual type IDictionary<string, object> me = (IDictionary<string, object>)client.Get(“me”); string firstName = (string)me[“first_name”]; //May use ‘me[“first_name”].ToString()’ string lastName = (string)me[“last_name”]; string email = (string)me[“email”]; solved rewrite this code to use in .NET … Read more
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
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
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
Its a simple math sum quiz that is asking the user for sum of same numbers from 1 to 10 The expected output is : What is 1 + 1? In every single iteration of the outer loop , after questioning like this , the program waits for the user input. When the user inputs … Read more
What does the arguments (char * &str1, char * &str2) specify in the swap function? they specify that parameters are of type reference to pointer to char. This means that function might change the value of the variable that was provided as argument to this function. What if they are replaced by (char &str1, char … Read more
An enum is basically a special type that lets you define named values. You’re creating a named type just as you would if you were defining a class. What your code is actually doing is first defining your enumerated type called States with all the possible named values, then declaring a variable “myState” using the … Read more
It’s simply how Java is specified. From JLS Sec 15.26, the grammar of the assignment is given by: Assignment: LeftHandSide AssignmentOperator Expression LeftHandSide: ExpressionName FieldAccess ArrayAccess So the LHS has to be either a variable, a field or an array element. Anything else is invalid syntax. The reason why you can’t reassign a method’s return … Read more
