Answer:
Ada Lovelace was the first computer programmer
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.
Answer:
a) Global
Explanation:
The scope of a variable declared outside of any function is Global.
Let us consider an example:
int g;
int add(int a,int b){
return a+b;
}
int subtract(int a,int b){
return a-b;
}
Here the variable g is defined outside any function and is accessible anywhere within the program. This is a global variable.
Variables defined within each function - a,b on the other hand have a local scope are are visible only within their respective function bodies.
It depends on the length of the words.
