Your question is a bit vague but I’m assuming you want to assign the first visited class found (if any) var class_name = new string[] {}; // I changed this line just to comply with coding best practices @foreach (string items in str_array) // str_array I am getting like [0] = 1 // [1] = … Read more
Two issues: 1) 060 is actually octal which in decimal is 48. So, remove all leading zeros. 2) Inside calculateCost change: if (line[0] == “Mo” || line[0] == “Tu” || line[0] == “We” || line[0] == “Th” || line[0] == “Fr”) to: if (day == “Mo” || day == “Tu” || day == “We” || … Read more

The issue is in the = in if conditions. = is the assignment operator whereas == is the equality comparision operator. When you assign a value to the int, it evaluates to true as well, and so the if condition is also satisfied. Also, as mentioned in the comments, change the data type from int … Read more
From what I see, it seems that you need a function that swaps position of every 2 bits in a number. few examples: 10’00’11’01’01 -> 01’00’11’10’10 11’01’10’10’11 -> 11’10’01’01’11 for this operation, a very simple function is following: unsigned int change_bit(unsigned int num) { return ((num & 0xAAAAAAAA) >> 1) | ((num & 0x55555555) << … Read more
I feel you should try to fully master one language before advancing to another. If you juggle too many at the same time you will just mix up their syntax and spend a lot of time becoming a jack of all trade and a master of non. 6 solved Should I learn C++ before I … Read more
In main, queen(ent);, rather than creating a temporary queen using the constructor taking an int, tries to create a queen object called ent using the default constructor. Since ent already exists as an int the compiler throws an error. The solution is to create the object like this: queen q(ent); 3 solved Passing an integer … Read more
First of all and most importantly: This is not good C++ code, not even decent. For example, some of your #includes are wrong, like <stdio.h> should be <cstdio> instead. The worst thing here are those #defines that make your code utterly unreadable. You really should read a good book on C++! For better readability I … Read more
You made a mistake in the formulae. The way you’re looking at it, you should write: (a + sqrt(b^2 + c^2)) (b + sqrt(a^2 + c^2)) (c + sqrt(a^2 + b^2)). And even then, you wouldn’t get the shortest distance. To give an example, suppose the cube is of 1x1x1 units with sides along the … Read more
The fastest way that the rumour will travel is when the roumor starts in the middle of the matrix. Since it travels only horizontally or vertically, if it starts from the middle then it will take m/2 + n/2 days to reach a corner in the worst case. Just try this printf(“%d\n”,m/2+n/2); it should work. … Read more
There are many statements in your code that literally DO NOTHING, 7+8+14; a+a2; b+b2; c+c2; d+d2; e+e2; f+f2; and answer=answer; You see, answer is uninitialized. You never set it’s value in the code, so you need something like // Initialize `answer’ here answer = 7 + 8 + 14; answer = answer + a + … Read more
