**Program to calculate Sum of negative and positive numbers** is to add all the positive and all the negative numbers present in the array.

**Positive number **

A number which is greater than 0 is the positive number(integer).

Numbers 0, 1, 2,……. are positive numbers.

**Negative number **

A number which is less than 0 is the negative number (integer).

Numbers -1, -2, -3 …. are negative numbers.

## Algorithm to find the Sum of negative and positive numbers

- Declare variables. N, array[], pos, neg
- Take a number from a user(positive and negative). array[N]
- Traverse array from i = 1 to end

If array[i] is positive

pos =+ array[i]

If array[i] is negative

neg =+ array[i] - Print sum of positive and negative number. pos, neg

## C program to find sum of positive and negative numbers

#include<stdio.h> main() { int i,size,pos=0,neg=0; float avg; printf("Enter the size of array\n"); scanf("%d",&size); int array[size]; printf("Enter numbers to find sum of positive and negative numbers\n"); for(i=0;i<size;i++) { scanf("%d",&array[i]); } for(i=0;i<size;i++) { if(array[i]>0) pos+=array[i]; if(array[i]<0) neg+=array[i]; } printf("The sum of positive inegers is %d\n",pos); printf("The sum of negative integers is %d\n",neg); }
