One last question: "Which statement correctly reads a single character and ignores whitespace?" She chose: scanf(" %c", &ch); — the space before %c consumes newline or space.
She hit . Input: 75 30 → Sum = 105. Output: HIGH . Good. Input: 20 40 → Sum = 60. Output: MEDIUMLOW — Error! c essentials part 1 module 3 test
Elena stared at the blinking cursor on her vintage terminal. She was one step away from passing Module 3 of her C programming certification. The test simulation presented a problem: "Write a program that reads two integers. If their sum is greater than 100, print 'HIGH'. If the sum is between 50 and 100 inclusive, print 'MEDIUM'. Otherwise, print 'LOW'." She smirked. Simple. She quickly typed: One last question: "Which statement correctly reads a
#include <stdio.h> int main() { int a, b, sum; scanf("%d %d", &a, &b); sum = a + b; if (sum > 100) printf("HIGH"); if (50 <= sum <= 100) printf("MEDIUM"); else printf("LOW"); return 0; } Output: HIGH
But the final test question was trickier: "What is the output of this code?" int x = 5; int y = 2; float z = x / y; printf("%f", z); She almost answered 2.5 , but caught herself. Integer division truncates. x / y = 2 , then stored as 2.000000 . The correct output: 2.000000 .
