c简单题目两道

1.计算0～101所有奇数与偶数并打印

#include<stdio.h>
#include<math.h>
int main(){
	int i=0;
	for (i = 0; i < 101; i++){
		if (i % 2 == 0){
			printf("%d\n", i+1);
		}
		else{
			printf("%d\t", i-1);
		}
	}
	
	return 0;
}

2.实现数组中值的交换

#include<stdio.h>
#include<math.h>
int main(){
	int count;
	int arr1[10] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };
	int arr2[10] = { 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 };
	
	for (int i = 0; i < 10; i++){
		count = arr1[i];
		arr1[i] = arr2[i];
		arr2[i] = count;
	}
	
	for (int i = 0; i < 10; i++){
		printf("%d\t%d\n", arr1[i], arr2[i]);
	}
	
	return 0;
}
