Question

Can this code be rewritten so that a switch statement isn't use but a loop instead. Thanks.

#include

#include

#include

using namespace std;

int main()

{

int N=0;

string s; //to read lines from file

int count[10]={0,0,0,0,0,0,0,0,0,0}; //initialize all digit counts to zeroes

string filename; //to store filename

//ask user to enter filename

cout<<"Enter a filename to analyze"<

cin>>filename;

//open inputfile

ifstream inputfile;

inputfile.open(filename.c_str());

//read firstline

inputfile>>s;

while(s!="-1"){

N++; //count total lines (Numbers)

int start_digit=s[0] - '0'; //take first digit of each string

//increment respective count

switch(start_digit){

case 0:

count[0]+=1;

break;

case 1:

count[1]+=1;

break;

case 2:

count[2]+=1;

break;

case 3:

count[3]+=1;

break;

case 4:

count[4]+=1;

break;

case 5:

count[5]+=1;

break;

case 6:

count[6]+=1;

break;

case 7:

count[7]+=1;

break;

case 8:

count[8]+=1;

break;

case 9:

count[9]+=1;

break;

}

inputfile>>s;

}

cout<

cout<<"N="<

//print count and percentage

for(int i=0;i<10;i++){

cout<

}

inputfile.close(); //close input file

return 0;

}

Explanation / Answer

The switch statement can be replaced with following loop statement.

for (i = 0; i<10; i++){
    if (start_digit == i){
       count[i] +=1;
    }
}
