Answer 1

// Sourcecode.c

#include<stdio.h>

int main(){
printf("Menu\n");
printf("1. To total numbers using a while loop\n");
printf("2. To total numbers using a do...while loop\n");
printf("Enter your menu choice: ");
  
int choice;
scanf("%d",&choice);

if(choice == 1){
int total = 0;
printf("How many numbers do you want to add: ");
int n;
scanf("%d",&n);

int a;
int i=1;
do{
printf("Enter a value for number %d: ",i);
scanf("%d",&a);
total += a;
i++;
}while(i<=n);
printf("The total is: %d",total);

}else if(choice == 2){
int total = 0;
printf("How many numbers do you want to add: ");
int n;
scanf("%d",&n);

int a;
int i=1;
while(i<=n){
printf("Enter a value for number %d: ",i);
scanf("%d",&a);
total += a;
i++;
}
printf("The total is: %d",total);
}
return 0;
}

// Output:
