Ques:-16) Write a program to enter the numbers till the user wants and at the end it should display the count of positive, negative and zeros entered.
Below is a C program that allows the user to enter numbers until they choose to stop. It then displays the count of positive numbers, negative numbers, and zeros entered.
#include<stdio.h>
#include<conio.h>
void main()
{
int x[],pos,neg,zero,i,n;
clrscr();
printf("How many number\n");
scanf("%d",&n);
printf("Enter all the numbers in the list\n");
pos=0;
neg=0;
zero=0;
for(i=0;i<n;i++)
{
scanf("\n%d",&x[i]);
}
for(i=0;i<n;i++)
{
if(x[i]>0)
pos++;
if(x[i]<0)
neg++;
if(x[i]==0)
zero++;
}
printf("Count of positive number is:%d\n",pos);
printf("Count of negative number is:%d\n",neg);
printf("Count of zeros is:%d\n",zero);
getch();
}

Another Example
#include <stdio.h>
int main() {
int num;
int positiveCount = 0, negativeCount = 0, zeroCount = 0;
char choice;
do {
printf("Enter a number: ");
scanf("%d", &num);
if(num > 0) {
positiveCount++;
} else if(num < 0) {
negativeCount++;
} else {
zeroCount++;
}
printf("Do you want to enter another number? (y/n): ");
scanf(" %c", &choice); // Note the space before %c to consume any newline character left in the input buffer
} while(choice == 'y' || choice == 'Y');
printf("\nCount of positive numbers: %d\n", positiveCount);
printf("Count of negative numbers: %d\n", negativeCount);
printf("Count of zeros: %d\n", zeroCount);
return 0;
}
Explanation:
Variable Declaration:
num: Stores the current number entered by the user.positiveCount,negativeCount,zeroCount: Counters for positive numbers, negative numbers, and zeros respectively.choice: Stores the user’s decision to continue entering numbers or not.
Input Loop:
- The
do-whileloop allows the user to enter numbers until they choose to stop. - After entering a number, the program checks if the number is positive, negative, or zero and increments the respective counter.
- The user is then prompted to enter another number or stop. If they enter ‘y’ or ‘Y’, the loop continues.
- The
Output:
- After the loop exits, the program prints the counts of positive numbers, negative numbers, and zeros.
Sample Output:
Enter a number: 5
Do you want to enter another number? (y/n): y
Enter a number: -3
Do you want to enter another number? (y/n): y
Enter a number: 0
Do you want to enter another number? (y/n): y
Enter a number: 2
Do you want to enter another number? (y/n): n
Count of positive numbers: 2
Count of negative numbers: 1
Count of zeros: 1
