Explanation:
In the given java code, an integer variable "i" and an array number is defined, which size is 10, in the next step two for loop is declared, that can be described as follows:
- In the first loop, array use loop variable "i" use, which minus the value of 5 and multiplies by 2, and it will calculate the square of that number.
- In the next step, a for loop is declared, that prints these array number variable square.
The third one because u have to do parenthesis
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.
