# C - Write program to output table of reciprocals, squares, cubes, and fourth powers.

## Requirements

Define a two-dimensional array, data[11][5], of type double.

Initialize the elements in the first column with values from 2.0 to 3.0 inclusive in steps of 0.1.

If the first element in a row has value x, populate the remaining elements in each row with the values 1/x, x*x , x*x*x , and x*x*x*x.

Output the values in the array with each row on a separate line and with a heading for each column.

## Demo

#include <stdio.h>

int main(void)
{
const size_t nrows = 11;              // Number of rows in the array
const size_t ncols = 5;               // Number of columns in the array
double data[nrows][ncols];            // Stores data values
double value = 2.0;                   // Value to be stored in array

for (size_t row = 0; row < nrows; ++row)
{//  w w w  .j av a 2s .  c  om
data[row][0] = value;
data[row][1] = 1.0 / data[row][0];               // 1/x
data[row][2] = data[row][0] * data[row][0];      // x*x
data[row][3] = data[row][2] * data[row][0];      // x*x*x
data[row][4] = data[row][3] * data[row][0];      // x*x*x*x
value += 0.1;
}

printf("            x  ");
printf("          1/x  ");
printf("          x*x  ");
printf("         x*x*x ");
printf("        x*x*x*x");

for (size_t row = 0; row < nrows; ++row)
{
printf("\n");
for (size_t col = 0; col < ncols; ++col)
printf("%15.4lf", data[row][col]);
}

printf("\n");
return 0;
}
