[ad_1] EDIT: Changed the while to a do-while, as this will always execute once, regardless of the initial value of a or b. It’s up to your preferences if you want to do it like this or with a while. Next to that, I have changed the parameters of the while from while (a == … Read more
[ad_1] 1) The array index start from 0, as per your code it will access matrice[2][2] which will cause undefined behavior. 2) matrice[a][b]=scanf(“%d”,&i); will store the return value of scanf in matrice[a][b]. #include <stdio.h> int main() { int a,b,matrice[2][2]; printf(“Put inside the matrix some numbers..\n”); for (a=1;a>=0;a–) { for (b=1;b>=0;b–) { scanf(“%d”,&matrice[a][b]); } } //Then … Read more
[ad_1] Functions in languages such as C# (and many, many, others) can take “parameters”. These are things you pass in to let the function do whatever it was designed to do. Consider: public int Add(int x, int y) { return x + y; } int a = 5; int b = 5; int sum = … Read more
[ad_1] This is your search function correctly formatted: int linearsearch (int A[] , int z, int n, int srchElement) { for (int z = 0; z < n; z++) { if(A[z] == srchElement) {return z;} } return -1; } and here is how you call it: index=linearsearch(A, n, srchElement, z); You pass a value z … Read more
[ad_1] If you simply want to call the IsRectangle() function, just add the following code between the next: and } lines: if (IsRectangle(x1, y1, x2, y2, x3, y3, x4, y4)) { printf(“The points define a rectangle.\n”); } else { printf(“The points do NOT define a rectangle.\n”); } However, as others have pointed out, there are … Read more
[ad_1] You can get the executing assembly path. string path = (new System.Uri(Assembly.GetExecutingAssembly().CodeBase)).AbsolutePath; From there, you can obtain the drive letter (path root): string drive = Path.GetPathRoot(path); If your file is in the same directory as the executable, you can get the file path like this: string directory = Path.GetDirectoryName((new System.Uri(Assembly.GetExecutingAssembly().CodeBase)).AbsolutePath); string databaseFile = Path.Combine(directory, … Read more
[ad_1] The first parameter to fputs is a char*, so the code you show is obviously incorrect. You say I tried itoa or sstream functions but it’s not working. but those are the solutions, and there’s no reason for them not to work. int a = 5; //the C way FILE* pFile = fopen(“myfile.txt”,”w”); char … Read more
[ad_1] Because you didn’t reference the variable using an object reference in your validClientId() method (as described by T McKeown’s answer), your code is looking within the scope of the validClientId() method itself to find that variable. It can’t find it because the variable hasn’t been declared within that scope. Try including the object reference … Read more
[ad_1] It’s of type FontStyle i.e. Enums are first class types. public enum FontStyle { Regular = 0; Bold =1; Italic = 2 } // No need to cast it FontStyle fontstyle = FontStyle.Bold; Edit: Perhaps you have code like this: if(1 == 1) FontStyle fontstyle = FontStyle.Bold; for your error (Embedded statement cannot be … Read more
[ad_1] If you just want to open an existing image using defualt app then use ShellExectue API. For example: ShellExecuteW(NULL, L”open”, L”Z:\\cat.PNG”, NULL, NULL, SW_SHOW); You could also open image with mspaint using the same API: ShellExecuteW(NULL, L”open”, L”C:\\Windows\\system32\\mspaint.exe”, L”Z:\\cat.PNG”, NULL, SW_SHOW); ShellExecuteEx will let you wait for finishing process. You can do the same … Read more
[ad_1] “Stack overflow” means that your recursive function calls itself too many times than the system can support it. Either you have an error, and recursion goes to infinity, or the function is correct, but just needs the depth that system currently can’t provide. We cannot tell which of the two is it until we … Read more
[ad_1] well the syntax was wrong, that’s all. It should be public static int CalculateAge(this DateTime bornDate). No dot between this and DateTime. But you absolutely need this when declaring an extension method, as every bit of documentation describing extension methods will say… – Jon Skeet [ad_2] solved DateTime does not contain a defintion for … Read more
[ad_1] This should fix your problem (if I understand the problem, that is): var number = decimal.Parse(“0,55”.Replace(‘,’, ‘.’), CultureInfo.InvariantCulture); EDIT Not every culture uses the point (.) symbol as the decimal separator. If you don’t specify a format provider, the framework defaults to the current culture. I’m guessing that in this particular case, the decimal.Parse() … Read more
[ad_1] EDIT: based on your edit the issue is that you’re using the parameters out of order. You need to switch the order and supply the input (string source to find a match in) then the pattern (what to match against). In fact, this order is specified for you by the IntelliSense as depicted in … Read more
[ad_1] [*] You could do something like this: #include<stdio.h> int main(void){ int int1, int2, sum=0; char op; printf(“Please enter one of the following Operators [*] [/] [+] [-] “); if((scanf(“%c”,&op)) != 1){ printf(“Error\n”); } printf(“Enter Value Here: “); if((scanf(“%d”, &int1)) != 1){ printf(“Error\n”); } printf(“Enter Value Here: “); if((scanf(“%d”, &int2)) != 1){ printf(“Error\n”); } if … Read more
