If Else Logic Basic Example

Code

int testscore = 76;
char grade;

if (testscore >= 90) {
	grade = 'A';
} else if (testscore >= 80) {
	grade = 'B';
} else if (testscore >= 70) {
	grade = 'C';
} else if (testscore >= 60) {
	grade = 'D';
} else {
	grade = 'F';
}
Dump("Grade = " + grade);

Result

Console

Grade = C
