在数组中选择范围，C

Question

所以我有数组，我应该计算索引1到5的平均值。索引0和6是用于另一个目的。有人可以帮我从这里出去吗？

代码：

int jumpnr = 0; 
int jumpval[7]; 

for (jumpval=0; jumpval<7; jumpval++){ 
jumpnr = jumpnr++ 
printf("Enter the jumpdistance for the %d",jumpnr); 
scanf(%d,&jumpval); 
} 

int average = jumpval[1] -> [5]; // <------- ? how 
printf("The average jumpdistance is: %d",average); 

Answer 1

在伪代码它会像

initialize an int called 'sum' and set it to 0 
for i from jumpval[1] to jumpval[5] 
    sum+=jumpval[i] 

了5分。然后总和会给你的平均水平。
