Explanation:
#include <iostream>
using namespace std;
void hex2dec(string hex_num){
int n = 0;
//Loop through all characters in string
for(int i=0;i<hex_num.size();i++){
//take ith character
char c = hex_num[i];
//Check if c is digit
if(c>='0' && c<='9'){
n = 16*n + (c-48);
}
//Convert c to decimal
else{
n = 16*n + (c-55);
}
}
cout<<hex_num<<" : "<<n<<endl;
}
int main()
{
hex2dec("EF10");
hex2dec("AA");
return 0;
}
The Output can be seen below :

Available options
=A4&&B4
=A4&" "&B4
="A4"&""&"34"
=A4&""&B4
Answer:
=A4&""&B4
Explanation:
In a Microsoft Excel spreadsheet, to combine the content of two cells into another cell, a user will have to use the command &
Hence, in this case, given that there is no need to have any character or blank space in between the content of the starging cells, which is just A4 and B4, then we have the following technique
1. Select the cell C2
2. Input the command = or +, then select cell A4
3. Input the command &
4. Then select the cell B4
5. Click enter.
Therefore, the answer should appear as =A4&B4.
But from the available options, there is nothing like that, so we pick =A4&""&B4 because it gives the same outcome.
