passing array to function code example
Example 1: how to pass an array to a function
#include <stdio.h>
float calculateSum(float age[]);
int main() {
float result, age[] = {23.4, 55, 22.6, 3, 40.5, 18};
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: array as parameter c++
void myFunction(int param[]) {
.
.
.
}
Example 3: passing array to function c++ pointer
void generateArray(int *a, int si)
{
for (int j = 0; j < si; j++)
a[j] = rand() % 9;
}
int main()
{
const int size=5;
int a[size];
generateArray(a, size);
return 0;
}
Example 4: how to accept an array as function parameter in c
#include <stdio.h>
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]);
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]);
}
}
}
