printf("\n enter the marks:");
scanf("%d",&n);
if(n>89)
printf("O");
else if(n>79)

Program explanation:-

1. enter your marks. for example we take 70
.
2.  then your input checks with 'if' block's condition. if it satisfied then it directly show the output.

3. if it doesn't satisfied then it goes to 'else-if' block's condition. if it satisfied with any else-if blocks then it show the grade as output.

4.if it doesn't satisfied  with any else-if block's condition then at last it goes to else block's condition.
