This is my problem. My task is to code the function void:
void process(char input[], char output[]){
}
And the given:
int main(){
const int MAX_SIZE = 100;
char input[] = "this is a beautiful day" ;
char output[MAX_SIZE];
process(input, output);
cout << output;
return 0;
}
Note: I just can use and for this question.
This is my work:
void process(char input[], char output[]){
int n = strlen(input);
for (int i = 0; i > n; i++){
output[i] = input[i];
input[i] = input[n - i + 1];
input[n - i + 1] = output[i];
}
}
But it doesn't work. How should I fix it?

Answer 1

there's a logical error with your code.
for (int i = 0; i > n; i++){
output[i] = input[i];
input[i] = input[n - i + 1];
input[n - i + 1] = output[i];
In your looping statement, you've initialised i=0 and given the condition i>n. This will result in the loop statement not executing.
Secondly, I have simplified your code further, and it should provide the required input.
for (int i = 0; i<=n; i++){
output[i] = input[n - i]; //1
cout<<output[i];
}
So essentially, a string is an array of characters, so to simplify, since the index in the array output is running from 0 to n, simultaneously, the array input indexes are being accessed from n to 0, in the line //1 .
As mentioned, since a string is an array of characters, within the same loop, i'm displaying each element in the output string. Providing the answer.
My test case was : This is a test
Output: tset a si sihT
Hope this helps! Let me know if you need any further explanation.
