im trying to Continue until the user enters a command they are ready to terminate the program using y/n i got it to terminate with "n" but when i use "y" it wont continue and ask for input from user
Transcribed Image Text:Enter 10 grades: 1 2 3 45 6 789 10
Standard Deviation = 2.872281
Mean= 5.500000
Range= 9.000000
Do you want to continue: y/ny
Do you want to continue: y/nn
![float cal(float grades []);//function declaration
int main(){//main function
//global declarction variables
i;//data type
float grades[10];
int
char ch;
printf("Enter 10 grades: ");// ask for input
scanf ("%f",&grades [0]);
float sum-grades [0];
float mean;
float big= grades [0];
float smal1 = grades [0];
float range;
for(i=1; i<10; ++i) //for loop
{
scanf(" %f", &grades [i]);//intake the input from user
sum +=grades[i];//stored and sum input
mean=sum/10; //compute mean

%.6f" ,cal(grades));//print output
do{
printf("Do you want to continue: y/n");
scanf(" %c", &ch);
if (ch=='y')
continue;
else if (ch=='n' )
exit(EXIT_SUCCESS);
}while(ch=='y');
