PROGRAMMING:Character array traversal

Analyze the following code to understand the traversal method of character array and string.
```
#include
int main(){
char s[26];
char t[100]="The People\'s Republic of China";
int i,j;
for(i=0; i<26; I + +) / / traverses the entire array assignment
s[i]='A'+i;
for(i=0; i<26; I + +) / / traverses the entire array output
printf("%c%c",s[i],s[i]+32);
printf("\n");
for(i=0; t[i]!='\ 0'; / / only traverses the string (not the entire array)
printf("%c_", t[i]);
return 0;
}
```
###Input example:
