while循环嵌套写1！+2！+3!+......+n!

n = int(input("请输入一个正整数："))
i = 1
while i <= n:
j = 1
result = 1
while j <= i:
result *= j
j += 1
print("{}! = {}".format(i, result))
i += 1

c语言while循环嵌套写1！+2！+3!+......+n!

#include <stdio.h>

int main() {
int n, i = 1, factorial = 1;
printf("Enter a number: ");
scanf("%d", &n);

while (i <= n) {
int j = 1, f = 1;
while (j <= i) {
f *= j;
j++;
}
printf("%d! = %d\n", i, f);
i++;
}

return 0;
}

循环嵌套示例及练习2:求1!+2!+3!+4!+5!(for循环嵌套while循环)

循环嵌套示例：

for (int i = 1; i <= 5; i++) {
    for (int j = 1; j <= i; j++) {
        printf("*");
    }
    printf("\n");
}

输出结果为：

练习2代码如下：

int sum = 0;
int i = 1;
while (i <= 5) {
    int j = 1;
    int factorial = 1;
    while (j <= i) {
        factorial *= j;
        j++;
    }
    sum += factorial;
    i++;
}
printf("1!+2!+3!+4!+5!=%d\n", sum);

输出结果为：

1!+2!+3!+4!+5!=153
