Here are three steps to find the greatest number among three number. You can choose one of them: 1. Using If Statement #include int main() { double n1, n2, n3; printf('Enter three different numbers: '); scanf('%lf %lf %lf', &n1, &n2, &n3); if (n1 >= n2 && n1 >= n3) printf('%.2f is the largest number.', n1); if (n2 >= n1 && n2 >= n3) printf('%.2f is the largest number.', n2); if (n3 >= n1 && n3 >= n2) printf('%.2f is the largest number.', n3); return 0; } 2. Using If...else statement #include int main() { double n1, n2, n3; printf('Enter three numbers: '); scanf('%lf %lf %lf', &n1, &n2, &n3); if (n1 >= n2 && n1 >= n3) printf('%.2lf is the largest number.', n1); else if (n2 >= n1 && n2 >= n3) printf('%.2lf is the largest number.', n2); else printf('%.2lf is the largest number.', n3); return 0; } 3. Using Nested If else #include int main() { double n1, n2, n3; printf('Enter three numbers: '); scanf('%lf %lf %lf', &n1, &n2, &n3); if (n1 >= n2) { if (n1 >= n3) printf('%.2lf is the largest number.', n1); else printf('%.2lf is the largest number.', n3); } else { if (n2 >= n3) printf('%.2lf is the largest number.', n2); else printf('%.2lf is the largest number.', n3); } return 0; } The output of all program is same: Enter three numbers: -4.5 3.9 5.6 5.60 is the largest number.
