[ad_1] You would store the line/string in a variable until you hit an \n. You would then, check if the string is equal, or even just contains, a single tab or, other chars also. That would be a good way, I think. I don’t know how hard this would be in C++, but I don’t … Read more
[ad_1] The problem in your program comes from the subject selection (after adding the missing }): s=random_number_creator(5,0); Will return a random number between 0 and 4 included. To correct this, just replace this line by s=random_number_creator(7,0); To pick a number between 0 and 6. So the cou variable will be able to reach 0 Your … Read more
[ad_1] What are you trying to do looks dangerous to me. Try to understand what those classes are for and ask some advice from a colleague. He will definitely help you on that. You will not find an answer here because your situation is too specific and we have no sample code. Also, some OOP … Read more
[ad_1] since object1 is a collection, how do you want to print the data. Assuming that you want to print each object in each line. for (int i = 0; i < object1.Count; i++) { Console.WriteLine(string.Concat(object1[i].item1, “—“, object1[i].Item2) } 1 [ad_2] solved How to get data from observablecollection and display into console application in c#?
[ad_1] try var firstChar = dr[“Value”].ToString()[0]; var ok = firstChar == ‘y’ || firstChar=”Y”; and make some performance-tests – but I don’t think that this will really be a issue at all. PS: assuming that the string is not empty – if this might be an issue make it var value = dr[“Value”].ToStrin(); var firstChar … Read more
[ad_1] If the line if (choice == “foodSize”) is working at all, then you are depending on compiler optimizations. What this is doing is comparing where in memory those two strings are located; if it is true, this is only because the compiler optimized them into two pointers to the same string. The correct way … Read more
[ad_1] you are passing reference to orig. you should use ‘orig.bigIntVector’ BigInt::BigInt(BigInt const& orig) : isPositive(orig.isPositive) , base(orig.base) , skip(orig.skip) { this->bigIntVector = new BigIntVector(*(orig.bigIntVector)); } should use *(orig.bigIntVector) 10 [ad_2] solved Copy Constructor Issue C++: “0xC0000005: Access violation writing location 0x00000000.”
[ad_1] The problem is that you return the inputed string at the end of the loop no matter the validation done. You can use a boolean to check this validity. Also you don’t need to parse all the string and you can break the inner loop on the first invalid char. I renamed the string … Read more
[ad_1] Since the pointer returned by malloc() is sufficiently well aligned to be used as a pointer to any type, you could (but probably shouldn’t) use: assert(sizeof(float) <= 10); void *data = malloc(10); char *str = data; strcpy(str, “123.4”); float *vp = data; *vp = strtof(str, NULL); …use *vp… free(data); And now you can use … Read more
[ad_1] The simplest way is for you to create an ordered collection of objects (a List<> for example) which you would redraw each time that the OnPaint event is called. Something like: // Your painting class. Only contains X and Y but could easily be expanded // to contain color and size info as well … Read more
[ad_1] Using std::copy(), it can be done like this: #include <iostream> #include <vector> #include <algorithm> void printVector(const std::vector<int>& v) { bool first = true; std::cout << ‘{‘; for (int i : v) { if (!first) std::cout << “, “; std::cout << i; first = false; } std::cout << “}\n”; } int main(void) { std::vector<int> v1 … Read more
[ad_1] The members of struct person are fixed in size, and are not allocated separately from the struct instance – short answer is that you cannot resize the arrays, nor can you deallocate their storage without deallocating the entire struct instance. The absolute best you can do in this case is to write an empty … Read more
[ad_1] so i ended up figuring it out. i ended up placing the graph in a different part of the code and got it working. for (int face = 2; face < arraysize; face++) { sum = ((sum + counter[face]) / 36000000) * 100; cout << setw(7) << face << setw(13) << counter[face] << setw(15) … Read more
[ad_1] There are 2 issues here: the last assignment uses input[index] instead of temp on the right hand side You iterate until the index reaches the end, which means every corresponding pair of indices is swapped twice resulting in the original string after fixing just (1.) if (!input.empty()) { for (size_t index = 0, index2 … Read more
[ad_1] Attempting to read an uninitialized variable that never had its address taken triggers undefined behavior, which basically means that the program is not required to behave in any particular way. It’s clear that you were attempting to have the uninitialized variable x in the function x to get the “left over” value of x … Read more
