1、总计和图形回答，15，# include math . h # include intmain()int I；双弹s；s=0；I=1；while(I=20)s=s 1.0/(2 * I *(2 * i1)*(2 * I2)；I=I 1；Printf(n%.3lf，s)；return 0；16，# include int main()long I；浮s；s=0；I=1；while(I=20)s=s 1.0/(2 * I-1)*(2 * I)*(2 * i1)；I=I 1；Printf(n%.3f，s)；return 0；25，#include int main() long i，sign双弹s；

2、sign=1；s=0；I=1；while(I=20)s=s 1.0/(2 * I-1)*(2 * I-1)*(2 * I-1)* sign；sign=-sign；I；Printf(n%.3lf，s)；return 0；26，# include int main()long I；双弹s；s=0；I=1；while(I=20)s=s 1.0/(I * I * I * I)；I；Printf(n%.3lf，s)；return 0；35，# include # include math . h intmain()long I；双s，x=0.5s=0；I=1；while(I=20)s=s sin(I *

3、 x)/(I * x)；I；Printf(n%.3lf，s)；return 0；36，# include # include math . h intmain()long I；双s，x=0.5s=0；I=1；while(I=20)s=s cos(I * x)/(I * x)；I；Printf(n%.3lf，s)；return 0；45，# include int main()long I；双弹s；s=0；I=1；while(1.0 *(i1)/I=1.01)s=s 1.0 *(i1)/I；I；s=s 1.0 *(I 1)/I；Printf(n%.3lf，s)；return 0；46，# inc

4、lude int main()long I；长s；s=3；I=2；While(s=1000 | s%7)！=0)s=s(2 * I-1)*(2 * I 1)；I；Printf(n%ld，s):Return 0；74，#include int main() int i，j；for(I=1)；I=4；I)for(j=1；j10-2 * I；j)printf()；for(j=1)；j=2 * I-1；J) printf(，64j)；printf(n)；return 0；75，#include int main() int i，j；for(I=1)；I=4；I)for(j=1；j10-2 * I；j)

5、printf()；for(j=1)；j=2 * I-1；J) printf(-，j)；printf(n)；return 0；78，#include int main() int i，j；for(I=1)；I=5；I)for(j=1；J10j)printf()；for(j=1)；j=6-I；J) printf(，96j)；printf(n)；return 0；79，#include int main() int i，j，k；for(I=1)；I=3；I)for(j=1；j=4；j)k=(I-1)* 4j；Printf(M，k)；printf(n)；return 0；80，# include ma

6、th . h # include intmain()int I，j，k；for(I=1)；I=5；I)for(j=1；j10 I；j)printf()；for(j=1)；J=10j)printf(*)；printf(n)；return 0；81，#include int main() int i，j；for(I=0)；i9；I)for(j=0；j9；j)if(I=j)printf()；else printf(*)；printf(n)；return 0；82，#include int main() int i，j；for(I=0)；i9；I)for(j=0；j9；j)if(I j=8)printf()；else printf(*)；printf(n)；return 0；83，#include int main() i
