Example: Write a program to read in the marks of a student and display the grade according to the following
information using else-if ladder.

Average Marks Grade

80 to 100 A
60 1௦ 79 B
50 to 59 (6
40 to 49 D
Oto 39 F(Fail).

This grading can be done using else-if ladder as follows:

if(marks > 79)
grade= 'A';
else if(marks > 59)
grade= 'B';
else if(marks > 49)
grade= 'C';
else if(marks > 39)
grade= 'D';
else
ഉദാ;

printf("Grade is %c",grade);

Program to find maximum of three numbers using else-if ladder.

main()

int a,b,c,max;
drscr();
printf("Enter values of a ,b,c");
scanf("%d%d%d" &a,&b, 80);
if(a>b && a>c)
max=a;
else if(b>c)

max=b;
