Question

Programming Question 1 Write a C program that takes students marks from a user, one by one until -1" is entered, which would indicate that no other marks are available, and the program terminates. For each mark the program will decide the student grade as: Fail, if mark < 60 • D. if 60<= mark <=70 • C. if 70<=mark <=80 • B. if 80c= mark <=90 • A. if 90cmark <=100 -T -- E - 15203 Arial T. T HE 31-0 . .

using C language

Answer 1

//Find Attached SS of Code and Output

#include <stdio.h>
int main()
{
float marks;
printf("Enter Student's Marks and Write -1 for Exit");
printf("\n");
//to get marks before entering in loop
scanf("%f", &marks);
//This will run until -2 is entered and it will keeping checking the if else conditions
while(marks!=-1){
if (marks < 60){
printf("Fail");
}
else if (marks > 60 && marks <= 70){
printf("D");
}
else if (marks > 70 && marks <= 80){
printf("C");
}
else if (marks > 80 && marks <= 90){
printf("B");
}
else if (marks > 90 && marks <= 100){
printf("A");
}
printf("\n");
//to take input of marks in loop
scanf("%f",&marks);
}
return 0;
}

mt no 000 1 #include <stdio.h> 2 int main() { float marks; printf("Enter Student's Marks and Write -1 for Exit"); printf("\n"); //to get marks before entering in Loop scanf("%f", Smarks); //This will run until -2 is entered and it will keeping checking the if else conditions while(marks !=-1){ if (marks < 60){ printf("Fail"); 13 else if (marks > 60 && marks <= 70){ printf("D"); 15 16 17 18 else if (marks > 70 && marks <= 80){ printf("C"); 19 else if (marks > 80 && marks <= 90){ printf("B"); 21 else if (marks > 90 && marks <= 100) { printf("A"); printf("\n"); //to take input of marks in Loop scanf("%f",&marks); return 0; }

Enter Student's Marks and Write -1 for Exit 89 B - 90 100 56 Fail ... Program finished with exit code 0 Press ENTER to exit console.
