Write a program to insert student grade and print the following
90 -> a
> 80 -> b
> 70 -> c
> 60 -> d
< 60 -> "fail"

The answer is the program, in the explanation

Explanation:

I am going to write a C program.

int main(){

int grade = -1; /*The grade will be read to this variable*/

/*This loop will keep repeating until a valid grade is inserted*/

while(grade < 0 || grade > 100){

         printf("Insert the student's grade: %n");

         scanf("%d", &grade);

}

/*The conditional according to the grade value*/

if (grade >= 90){

     printf("Your grade is A\n");

}

else if (grade >= 80 && grade < 90){

     printf("Your grade is B\n");

}

else if (grade >= 70 && grade < 80){

     printf("Your grade is C\n");

}

else if (grade >= 60 && grade < 70){

     printf("Your grade is D\n");

}

else{

    printf("You got a failling grade\n");

}

return 0;

}
