C break
The break statement ends the loop immediately when it is encountered. Its syntax is:
break;How break statement works?
Example:
// Program to calculate the sum of numbers (10 numbers max)
// If the user enters a negative number, the loop terminates
#include <stdio.h>
int main() {
int i;
double number, sum = 0.0;
for (i = 1; i <= 10; ++i) {
printf("Enter n%d: ", i);
scanf("%lf", &number);
// if the user enters a negative number, break the loop
if (number < 0.0) {
break;
}
sum += number; // sum = sum + number;
}
printf("Sum = %.2lf", sum);
return 0;
}Output:
Enter n1: 2.4`` Enter n2: 4.5 Enter n3: 3.4 Enter n4: -3 Sum = 10.30`
C continue
The continue statement skips the current iteration of the loop and continues with the next iteration. Its syntax is:
continue;How continue statement works?
Example:
// Program to calculate the sum of numbers (10 numbers max)
// If the user enters a negative number, it's not added to the result
#include <stdio.h>
int main() {
int i;
double number, sum = 0.0;
for (i = 1; i <= 10; ++i) {
printf("Enter a n%d: ", i);
scanf("%lf", &number);
if (number < 0.0) {
continue;
}
sum += number; // sum = sum + number;
}
printf("Sum = %.2lf", sum);
return 0;
}Output:
Enter n1: 1.1
Enter n2: 2.2
Enter n3: 5.5
Enter n4: 4.4
Enter n5: -3.4
Enter n6: -45.5
Enter n7: 34.5
Enter n8: -4.2
Enter n9: -1000
Enter n10: 12
Sum = 59.70
