Hi all
I have ben trying most of the day but i just don't understand how to do this,

So far i figure out i need to array of chars so i started with

so for example:

Code:

#include <stdio.h>
#include <string.h>


main(){
char name[25];

printf("what is your name?");
scanf("s%", &name);
printf("welcome, c%", name);

}

but this returns odd characters and not what was entered

Could anyone show me where am going wrong

Code:

#include <stdio.h>
#include <string.h>


main(){
char name[25];

printf("what is your name?");
scanf("%s", &name);
printf("welcome, %s\n", name);

}

This worked just fine for me (the newline character makes the output look nicer as well)

another way to do it, using fgets, which you should be using if you're just doing simple stuff in C

Code:

#include <stdio.h>
#include <string.h>


main(){
char name[25];

printf("what is your name?");
fgets(name, sizeof(name), stdin);
printf("welcome, %s", name);

}

I recommend the second one.

Indeed, scanf is totally garbage.
