I've got this:
int i, j, w;
char *array[50];
int main ()
{
array[1]= "Perro";
array[2]= "Gato";
array[3]= "Tortuga";
array[4]= "Girafa";
array[5]= "Canario";
array[6]= "Rata";
array[7]= "Leon";
array[8]= "Tigre";
array[9]= "Rinoceronte";
array[10]= "Mosquito";
for (i=1; i<11; i++)
{
开发者_运维问答 printf("El elemento %i es %s \n", i, array[i]);
}
printf("Escoja el elemento deseado");
scanf("%i", &w);
int c;
scanf("%i",&c);
return i;
}
Now I want something like this: printf("Desired Element %c, array[w]); but it fails, why?
printf("Desired Element %c", array[w]);
will try to print a character (%c), but it will fail since array[w] contains a string.
Try using %s instead:
printf("Desired Element %s", array[w]);
Probably because it's not %c
but %s
for strings
printf("Desired Element %d\n", array[w]);
Don't forget to check wether w
is valid.
Don't print the friend name (a string) as character (%c
), use %s
.
Also, arrays in C start at index 0, making them start at 1 instead is weird and might make it easier to confuse yourself and access past the end.
the %c
element in your debug string prints a character. If you want to print the string try:
printf("Desired Element %s", array[w]);
Use printf("Desired Element %s, array[w])
instead of with %c. You're printing a string, not a character.
There are many oddities in the program. Here is a cleaned-up version.
#include <stdio.h> /* necessary for printf/scanf */
#define ARRAY_LENGTH 10 /* use a constant for maximum number of elements */
int main ()
{
/* Declare all variables inside main(), at the very top. Nowhere else. */
int i;
int desired; /* use meaningful variable names, not x,y,z,etc */
char *array[50];
array[0]= "Perro"; /* arrays start at index 0 not 1 */
array[1]= "Gato";
array[2]= "Tortuga";
array[3]= "Girafa";
array[4]= "Canario";
array[5]= "Rata";
array[6]= "Leon";
array[7]= "Tigre";
array[8]= "Rinoceronte";
array[9]= "Mosquito";
for (i=0; i<ARRAY_LENGTH; i++) /* keep the loop clean */
{
printf("El elemento %i es %s\n\n", i+1, array[i]); /* instead, add +1 while printing */
}
printf("Escoja el elemento deseado: ");
scanf("%i", &desired);
getchar(); /* discard new line character somehow */
printf("El elemento %i es %s\n", desired, array[desired-1]);
getchar(); /* wait for key press before exiting program */
return 0; /* always return 0 */
}
