array of function in c code example
Example 1: how to pass an array to a function
// Program to calculate the sum of array elements by passing to a function
#include
float calculateSum(float age[]);
int main() {
float result, age[] = {23.4, 55, 22.6, 3, 40.5, 18};
// age array is passed to calculateSum()
result = calculateSum(age);
printf("Result = %.2f", result);
return 0;
}
float calculateSum(float age[]) {
float sum = 0.0;
for (int i = 0; i < 6; ++i) {
sum += age[i];
}
return sum;
}
Example 2: how to accept an array as function parameter in c
#include
void displayNumbers(int num[2][2]);
int main()
{
int num[2][2];
printf("Enter 4 numbers:\n");
for (int i = 0; i < 2; ++i)
for (int j = 0; j < 2; ++j)
scanf("%d", &num[i][j]);
// passing multi-dimensional array to a function
displayNumbers(num);
return 0;
}
void displayNumbers(int num[2][2])
{
printf("Displaying:\n");
for (int i = 0; i < 2; ++i) {
for (int j = 0; j < 2; ++j) {
printf("%d\n", num[i][j]);
}
}
}
Example 3: array of array in c
int a[3][4] = {
{0, 1, 2, 3} , /* initializers for row indexed by 0 */
{4, 5, 6, 7} , /* initializers for row indexed by 1 */
{8, 9, 10, 11} /* initializers for row indexed by 2 */
};
Example 4: c language array
int array[5]={1,2,3,4,5};
