help with array

[ayman723]

hi all;

I need help with this simple program;

I was asked to declare an array of int type called value with 5 elements [ 2,4,6,8,10] . I want to use while structre to change the value of each element in the array to be the square of its original value. I made this code, but its not working,

# include < iostream >

int main()
{
int value []= { 2,4,6,8,10 };
int i=0 ,i++;

while ( i<5 )
{

std::cout<< value [i] * value [i]<<std::endl;
}

return 0;


}


thanks in advance

The problem is in the statement
int i=0 ,i++;


The correct code is given below

# include < iostream >

int main()
{
int value []= { 2,4,6,8,10 };
int i=0;
while ( i<5 )
{
std::cout<< value [i] * value [i]<<std::endl;
i++;
}
return 0;
}

The increment should be inside the while statement.

Actually, he said he wanted to change each value in the array to it's square. The above program outputs the square value, but doesn't change it in the array.

# include < iostream >
 
int main()
{
  int value []= { 2,4,6,8,10 };
  int i=0;
  while ( i<5 )
  {
    value[i] *= value[i];
    std::cout << value[i] <<std::endl;
    i++;
  }
return 0;
}
