寻找给定列表的中位数的C程序

for (i = 1 ; i <= n-1 ; i++){ for (j = 1 ; j <= n-i ; j++){ if (a[j] <= a[j+1]){ t = a[j]; a[j] = a[j+1]; a[j+1] = t; } else continue ; } }

if ( n % 2 == 0) median = (a[n/2] + a[n/2+1])/2.0 ; else median = a[n/2 + 1];

#include #define N 10 main( ){ int i,j,n; float median,a[N],t; printf("Enter the number of items

",n); for (i = 1; i <= n ; i++) scanf("%f", &a[i]); /* Sorting begins */ for (i = 1 ; i <= n-1 ; i++){ /* Trip-i begins */ for (j = 1 ; j <= n-i ; j++) { if (a[j] <= a[j+1]) { /* Interchanging values */ t = a[j]; a[j] = a[j+1]; a[j+1] = t; } else continue ; } } /* sorting ends */ /* calculation of median */ if ( n % 2 == 0) median = (a[n/2] + a[n/2+1])/2.0 ; else median = a[n/2 + 1]; /* Printing */ for (i = 1 ; i <= n ; i++) printf("%f ", a[i]); printf("

Enter the number of items 5 Input 5 values 2.3 1.2 3.8 4.6 8.9 8.900000 4.600000 3.800000 2.300000 1.200000 Median is 3.800000
