If you do not provide any constructor in your class, the compiler will automatically create one for you. In your class, you have specified a particular constructor: MonthData(double, int, double, double, int, double, double); As soon as you provide any constructor, the compiler will not create a default constructor (i.e. one that takes no parameters). … Read more
This is a corrected version of your code. int add(int n, int a[10]) { if (n < 0) return 0; if (a[n] % 2 == 0 && a[n] > 0) return a[n] + add(n-1, a); else return add(n-1, a); } Note that the correct way to call the function for an array of length 10 … Read more
array is not out of bound Correct. The program has undefined behavior for another reason. I assume you are confused about this part: arr[1, 2] The 1,2 is comma seperated expressions, i.e. 1 and 2. The rule of the comma operator is that the result is the result of of the right operand. So 1,2 … Read more
You have declared string as a single character but you fill it with a string. This invokes undefined behavior. You should change your code to : char string [20] = “default”; //20 is random, you should use the maximum length of the input you may have printf(“The default String is: %19s”, string); scanf(“%s”, string); printf(“You … Read more
You can’t use strcasecmp to compare characters. It’s not completely wrong, but a single character is not a properly terminated string. If you must do comparison this way, use strncasecmp: if(strncasecmp(&gender,&word_M, 1) == 0) That will limit it to comparing one character. Also, your retry loop doesn’t check for ‘F’, but checks ‘M’ twice. solved … Read more
Try this: string myStr= “46917 – Shampoo”; if (myStr.Contains(‘-‘)) { string[] tokens = myStr.Split(‘-‘); int i = Convert.ToInt32(tokens[0].Trim()); } solved Split string and convert to integer in C#
You have put a ; at the end of for loops and that’s the reason the body of the for loop is not being executed as expected. Effect of semicolon after ‘for’ loop for (i = 0; i < strlen(test) && (test[i] == ‘-‘); i++); for (; i < strlen(test);); for (; (i < strlen(test)) … Read more
value is an array of integer, it can’t be zero. Any element in the array could be zero. If you are trying to determine if the array is null, then you could change the check to be: if (value == null) { Environment.Exit(1); } 1 solved Define if statement for property in C# [closed]
The ampersand (&) in a declaration declares a reference type, not a pointer. The ampersand (&) in an expression is the address of operator, which yields a pointer. Just because the same token is used in the language for two different things does not mean they are related things. Unfortunately, especially for learners. 0 solved … Read more
You should just use OAuth2 and follow the recommended process by facebook. Have a look at the documentation of the facebook graph API here. Remember to create a facebook developer account here. If youre using ASP.NET, there is an included Facebook OAuth2 client. Have a look at this link here. Its actually pretty easy to … Read more
Let’s try to explain *x = *y; without using the word “dereference”: *x represents the integer object pointed to by x. As it is the left operand of the assignment, it means that this integer object is going to be updated. *y represents the integer object pointed to by y. As it is the right … Read more
In the first code fragment, you are not assigning to d at all. Assignment (=) operator assigns the rvalue (right hand side) to the lvalue (left hand side). This is very standard syntax. solved if-else statement only works in a specific order and I don’t know why [closed]
I tested it in VS and this works for me: textBox1.Text = textBox1.Text.Replace(“\””, “\”\””); It replaces all ” with “” in my textbox. 2 solved string.replace( char, char) [closed]
