请生成一段c语言，输入长度N，信源01出现的概率，二进制对称信道BSC的差错概率，输出不同差错概率下的误码率丢包率

Sure, here's the code you requested:

#include<stdio.h>
#include<math.h>

int main(){
    int N;
    float p, q;
    printf("Please enter the length N, probability of source signal (p) and error probability of binary symmetric channel (q): ");
    scanf("%d%f%f", &N, &p, &q);

    printf("Different error probability:\n");
    printf("Error Probability\t\tBit Error Rate\t\tPacket Loss Rate\n");

    for (float e = 0; e <= 1; e += 0.1) {
        float ber = 0;
        float plr = 0;
        for (int i = 0; i < N/2; i++) {
            if ((((float) rand())/((float) RAND_MAX)) < e) {
                ber += 2;
            }
        }
        ber /= N;
        plr = pow((1-q), ber*N);
        printf("%.1f\t\t\t\t%f\t\t\t\t%f\n", e, ber, plr);
    }
    return 0;
}

Hope this helps!
