If I enter age more than 70 my else block isn't executing. Why?

Question

#include <stdio.h>
int main(int argc, char **argv)
{
int age;
printf("Enter your age: ");
scanf("%d", &age);
printf("You entered %d as your age\n", age);

if (age >= 18 && age <= 70){
printf("You can Drive!\n");
}

else if (age > 15){
// printf("Your age is %d\n", age);
if (18-age > 1){
printf("You can drive after %d years", 18-age);
}
if (18-age == 1)
{
printf("You can drive after %d year", 18-age);
}
}

else{
printf("You cannot Drive\n");
}
return 0;
}

Answer 1

If you enter more than 70 then first if condition age<=18 && age <= 70 false but else if condition age > 15 is true but again inner if conditions both false so won't output next anything.

Last else part works only if input is not above 15

You have
if ( ... )
{
..
}
else if( ... ) {
...
}
else {
..
}

So it's all depends on your logic..

Answer 2

Look at else if block.
If you enter 70, the if clause is false.
So it goes to else if clause. Is 70 > 15? True. So there is the problem.
Your else if clause should look like this: else if (age > 15 && age < 18)
Hope this helps.
