Explanation:
private void btnDelete_Click(object sender, EventArgs e)
{
if (this.dataGridView1.SelectedRows.Count > 0)
{
dataGridView1.Rows.RemoveAt(this.dataGridView1.SelectedRows[0].Index);
}
}
Answer:
many forms
Explanation:
Polymorphism is a construct in object oriented programming which means multiple forms.For example: Suppose I have a function which performs the add operation on two integers and another function with the same name which concatenates 2 given strings:
- string add ( string a , string b)
The two functions represent polymorphic forms of the add function. The function to be invoked at runtime is determined by the runtime argument type.
For example , add (2,3) will invoke int add ( int a, int b);
Similarly, add("hello","world") will invoke string add ( string a , string b);
Answer:
Running RECURSIVE-MATRIX-CHAIN is asymptotically more efficient than enumerating all the ways of parenthesizing the product and computing the number of multiplications of each.
the running time complexity of enumerating all the ways of parenthesizing the product is n*P(n) while in case of RECURSIVE-MATRIX-CHAIN, all the internal nodes are run on all the internal nodes of the tree and it will also create overhead.
Explanation:
Answer: a practice similar to piracy but in other contexts, especially hijacking.
"air piracy"
the unauthorized use or reproduction of another's work.
Explanation:
A formula is statement written by the user to be calculated. Formulas can be as simple or as complex as the user wants. A formula can contain values, references to cells, defined names, and functions.
All formulas must start with the equals sign. =1+2+3
A function is a piece of code designed to calculate specific values and are used inside formulas. Functions to sum values, calculate a trigonometric cosine, and to calculate the current time are built into excel. Additional functions can be defined using Visual Basic.
Functions are typed alongside parenthesizes, where in the arguments if any are listed in between. To use functions in a formula, for example
=COS(3.14) will return the calculated cosine. =NOW() returns the current time. =SUM(1+2+3) *2 will multiply the sum by 2Explanation hope it helps
