Solution for Exercise 9-5

ex0905

#include <stdio.h>

int main()
{
    int duo;

    for(duo=2;duo<=100;duo=duo+2)
    {
        printf("%d\t",duo);
    }
    putchar('\n');
    return(0);
}

Output

2    4     6     8     10    12    14    16    18    20    2
2    24    26    28    30    32    34    36    38    40    4
2    44    46    48    50    52    54    56    58    60    6
2    64    66    68    70    72    74    76    78    80    8
2    84    86    88    90    92    94    96    98    100

Notes

* The sample output above reflects an approximation of what you see on a standard 80-column display. The output is really one long line of text, which wraps at the 80th column.

* The third part of a for statement doesn't always have to increment the counter variable by one.
