Declaring arrays in c language without initial size
- by user2534857
this is the question--
Write a program to manipulate the temperature details as given below.
- Input the number of days to be calculated. – Main function
- Input temperature in Celsius – input function
- Convert the temperature from Celsius to Fahrenheit.- Separate function
- find the average temperature in Fahrenheit.
how can I make this program without initial size of array ??
#include<stdio.h>
#include<conio.h>
void input(int);
int temp[10];
int d;
void main()
{
int x=0;
float avg=0,t=0;
printf("\nHow many days : ");
scanf("%d",&d);
input(d);
conv();
for(x=0;x<d;x++)
{
t=t+temp[x];
}
avg=t/d;
printf("Avarage is %f",avg);
getch();
}
void input(int d)
{
int x=0;
for(x=0;x<d;x++)
{
printf("Input temperature in Celsius for #%d day",x+1);
scanf("%d",&temp[x]);
}
}
void conv()
{
int x=0;
for(x=0;x<d;x++)
{
temp[x]=1.8*temp[x]+32;
}
}
