Your fill function takes the parameter a by value, which means a copy is made. No changes to a inside the function will affect the variable you passed to the function. I suggest you make the function pass the object by reference: void fill(stack<int>& a, int cap) Now changes to a will update the object … Read more
You could use Task.Run() to start and get a reference to a new Task: public IdentityResult Validate( AppUser item ) { IdentityResult result; // do stuff return result; } public override Task<IdentityResult> ValidateAsync( AppUser item ) { return Task.Run( () => Validate(item) ); } solved how to return method which has task return type
The roll number string in your where clause needs to be delimited as a string. This line query = query + ” ” + “WHERE rollNo=” + “2K12-BSCS-37″; should be replaced with query += ” ” + “WHERE rollNo=” + “‘2K12-BSCS-37′”; Note the single quotes. Better still would be to use string format to build … Read more

When you don’t pass an object with ref keyword then object reference is passed by value. Whereas, in other case object is passed by reference. You can get better explanation with following example.

Actually I could not find the exact problem in your program, but if you want a program to perform quicksort on an array of elements, this is it: #include<stdio.h> void quicksort(int [10],int,int); int main(){ int x[20],size,i; printf(“Enter size of the array: “); scanf(“%d”,&size); printf(“Enter %d elements: “,size); for(i=0;i<size;i++) scanf(“%d”,&x[i]); quicksort(x,0,size-1); printf(“Sorted elements: “); for(i=0;i<size;i++) printf(” … Read more

You have you rows and columns mixed up. You have s[i][j] when it should be s[j][i].Also, as far as int s[n-1][m-1]; goes, I believe that you’re initializing this wrong. While an array starts at index 0 and goes to index (size – 1), when you initialize it, it should be array[enteredSize], not array[enteredSize – 1]. … Read more

There is not a way to return more than one redirect. It wouldn’t make sense, as one redirect would be processed right after the other, resulting in only the final redirect being effective. If you want to incorporate two pages into one, you can use partial views. solved Returning two RedirectToAction from controller C#.net MVC
