Answer:
a) printf("%-5.3e",x);
b) printf("%10llu",x);
<h3>
Explanation:</h3>
We can assign any value to x at the start of program:
For Example:
float x = 72.149;
Then in order to print exponential notation, left justified, in field size of 5 with 3 digits after the decimal point, we need to use the following format:
printf("%-5.3e",x);
where e represent exponential notation.
5 represents field size of 5 and 3 represents digits after decimal point.
In order to print x as right justified, in a 11 digit field, we need to use the following format:
printf("%10llu",x);
