设计一个算法，求一维数组float a[n]中所有元素之和，写出相应C程序？急

Answer 1

C程序如下：```cfloat array_sum(float a[], int n){ int i; float sum=0; for(i=0;i<n;i++) { sum+=a[i]; } return sum;}``

Answer 2

#include <stdio.h>

float sum_array(float a[], int n) {
float sum = 0;
for (int i = 0; i < n; i++) {
sum += a[i];
}
return sum;
}

int main() {
float a[] = {1.2, 2.3, 3.4, 4.5, 5.6};
int n = sizeof(a) / sizeof(float);
float sum = sum_array(a, n);
printf("数组元素之和为：%.2f\n", sum);
return 0;
}
