int main() {
    float score[6][6] = {0};
    double sum = 0;
    for (int i = 0; i < 5; i++) {
        sum = 0;
        for (int j = 0; j < 5; j++) {
            scanf("%f",&score[i][j]);
            sum += score[i][j];
        }
        score[i][5] = sum;
    }
    for (int i = 0; i < 5; i++) {
        for (int j = 0; j < 6; j++) {
            printf("%.1f ", *(*(score + i)+j) );
        }
        printf("\n");
    }
    return 0;
}

so easy!!!!
