Solution for Exercise 12-18
ex1218
#include <stdio.h> #define SIZE 3 int main() { char president[SIZE][8] = { "Clinton", "Bush", "Obama" }; int x,index; for(x=0;x<SIZE;x++) { index = 0; while(president[x][index] != '\0') { putchar(president[x][index]); index++; } putchar('\n'); } return(0); }
Notes
* The while loop's condition may throw you, simply because of the extra apparatus required to reference an individual element in a multidimensional array. The item president[x][index]
refers to a single charterer. The president[x]
is a row, or in this example, a string representing a President's name. The [index]
is the column of that row, representing a single character. Well, actually, the entire construction represents a single character, but it helps if you break it out to see how each character is referenced.
* The char array initialization at Line 7 (and through Line 10) is yet another way to declare an initialized array.
