Answer: D. Silver (happy to help)
Explanation:
public static void main()
{
String s = Console.ReadLine();
int len = s.length();
Char startletter = s[0];
Char endletter = s[len-1];
string midletter = ‘’;
if(len % 2 ==0)
midletter = s[len/2] + s[(len/2) +1]
else
midletter = s[len/2];
Console.WriteLine(startletter + midletter + endletter);
}
Here the logic is that, startletter is obtained using the index ‘0’, the last letter is obtained by calculating the “length of the string” and subtract 1 to get the “last index” of the given string.
Middle letter is calculated by first finding whether the given string length is “odd or even” and based on that index(es) are identified.
Answer: Naming the function
Explanation:
The first item for defining the function is the naming of the function. In the function, the first line is known as header and rest of the function is known as body of the function.
The function name is the first step while defining the proper function as we can define the actual function name on which the program are rest based.
We can define a function from which the each value from the set of the components are basically associated with the second component in that particular function.
Answer:
#include <iostream>
using namespace std;
int main() {
int a[4][5];//declaring a matrix of 4 rows and 5 columns.
for(int i=0;i<4;i++)
{
for(int j=0;j<5;j++)
{
if(i==3)//initializing last row as 0.
{
a[i][j]=0;
}
else//initializing last row as 1.
{
a[i][j]=1;
}
}
}
for(int i=0;i<4;i++)
{
for(int j=0;j<5;j++)
cout<<a[i][j]<<" ";//printing the matrix.
cout<<endl;
}
return 0;
}
Output:-
1 1 1 1 1
1 1 1 1 1
1 1 1 1 1
0 0 0 0 0
Explanation:
I have created a matrix of size 4 rows and 5 columns.I have used for loops to fill the array.To fill the last row with 0 i have used if statement.else we are filling it with 1.
