Name and age should be entered by the user. You have prepared the following code for this purpose. However, when testing it, you notice that errors have crept in. What is wrong? ------------------------- int age; char name[50];

printf("Name: "); scanf("%s", name);

printf("Age: ") scanf("%d", age);

1 : The placeholders in scanf are interchanged 2 : The order of the parameters in scanf is swapped 3 : The address operators in scanf are missing: &name and &age 4 : The address operators in scanf are missing, but only in &age 5 : scanf is the wrong function, it only works for files.
