Because contour lines represent elevation and you can't have two different elevations at the same point
Answer:
#include <stdio.h>
#include <string.h>
int main(){
char number[100];
printf("Number: ");
scanf("%s", number);
int sum = 0;
for(int i =0;i<strlen(number);i++){
sum+= number[i] - '0';
}
printf("Sum: %d",sum);
return 0;
}
Explanation:
This declares a c string of 100 characters
char number[100];
This prompts user for input
printf("Number: ");
This gets user input
scanf("%s", number);
This initializes sum to 0
int sum = 0;
This iterates through the input string
for(int i =0;i<strlen(number);i++){
This adds individual digits
sum+= number[i] - '0';
}
This prints the calculated sum
printf("Sum: %d",sum);
return 0;
I believe it is the first one, i did some research for this question
D(in a .c file ) because that is where it should be placed :)
