Explanation:
You are not putting the question but I can guess that it asking for the CD duration. To answer this question, you need to convert the CD capacity unit(783.216 megabyte) into megabits which were used for the cd read rate (1.4 megabits/s). The calculation would be:
CD duration: CD capacity / rate= 783.216 megabytes *(8 megabits/megabyte) / (1.4 megabits /s)= 4475.52 second or 74.6 minutes
Explanation:
#include<iostream>
#include<string.h>
using namespace std;
char *removestring(char str[80])
{
int i,j,len;
len = strlen(str);
for( i = 0; i < len; i++)
{
if (str[i] == ' ')
{
for (j = i; j < len; j++)
str[j] = str[j+1];
len--;
}
}
return str;
}
int main ()
{
char str[80];
cout << "Enter a string : ";
cin.getline(str, 80);
strcpy(removestring(str), str);
cout << "Resultant string : " << str;
return 0;
}
In this program the input is obtained as an character array using getline(). Then it is passed to the user-defined function, then each character is analyzed and if space is found, then it is not copied.
C++ does not allow to return character array. So Character pointer is returned and the content is copied to the character array using "strcpy()". This is a built in function to copy pointer to array.
A solid white line means no passing or changing lanes. Hope this helps.
