I am getting an undeclared identifier error for the string text although I identified it previously.
I am trying to create the for loop to run between 0 and strlen(text). Does anyone know what I am missing?
#include <cs50.h>
#include <stdio.h>
#include <ctype.h>
#include <math.h>
#include <string.h>
#include <stdlib.h>
int main(int argc, string argv[])
{
int key = atoi(argv[1]);
printf("%i\n", key);
if (argc != 2)
{
printf("Usage: ./ceasar key\n");
}
else
{
string text = get_string("Plaintext: ");
}
for(int i = 0, len = strlen(text); i < len; i++)
{
}
}
>Solution :
Your "string text" variable is only getting defined within the else statement, so you need to move your for loop into the same else statement:
int main(int argc, string argv[])
{
int key = atoi(argv[1]);
printf("%i\n", key);
if (argc != 2)
{
printf("Usage: ./ceasar key\n");
}
else
{
string text = get_string("Plaintext: ");
for(int i = 0, len = strlen(text); i < len; i++)
{
}
}
}
