Stupid Question Probably

i got a question lets say this program for example.

Code:

---

#include <stdio.h>

int main(void){
                signed int foo = 1;
               
                printf("foo is %i", foo);
                return 0;
}

---

isn't it that same as

Code:

---

#include <stdio.h>

int main(void){
                int foo = 1;
               
                printf("foo is %i", foo);
                return 0;
}

---

cause int is signed and the only way it would be different is unsigned so wouldn't it be better to just use int foo = 1; instead of signed int foo = 1;?

Yes, int's are always signed unless you say unsigned.

The same is not true for chars, which may be signed or unsigned (by default)

yeah i know that char care different so its really useless to use signed int foo; cause its signed by default right?
