Solution for Exercise 12-6

ex1206

#include <stdio.h>

int main()
{
    float marketclose[] = { 24164.95, 24107.08, 24643.63, 24400.93, 23728.53 };
    int day;

    puts("Stock Market Close");
    for(day=0;day<5;day++)
        printf("Day %d: %.2f\n",day+1,marketclose[day]);
    return(0);
}

Output

Stock Market Close
Day 1: 24164.95
Day 2: 24107.08
Day 3: 24643.63
Day 4: 24400.93
Day 5: 23728.53

Notes

* Another popular way to initialize an array is to place its elements on lines by themselves. For example:

float marketclose[] = { 14450.06, 14458.62, 14539.14, 14514.11, 14452.06 };

* The final curly bracket can go on a line by itself if you like, just remember not to place a comma after the final value in the array or the compiler thinks you goofed up and missed a value:

float marketclose[] = { 14450.06, 14458.62, 14539.14, 14514.11, 14452.06 };

* It's also common to organize array elements into rows and columns when they're initialized:

float marketclose[] = { 14450.06, 14458.62, 14539.14, 14514.11, 14452.06 };

* I hope you remembered to set marketclose[] as an array of float values.

* In Line 10 (the printf() statement), you see the day+1 construction, which outputs the looping value using the human method of starting at 1 instead of zero.
