1、Sy7-1#include#includevoidsub(chars[],chart[]){inti,d;d=strlen(s);for(i=0;i

2、2#include#include#defineARR_SIZE80voidInverse(charstr[]);main(){chara[ARR_SIZE];printf("pleaseenterastring:");gets(a);Inverse(a);printf("Theinversedstringis:");puts(a);}voidInverse(charstr[]){intlen,i=0,j;chartemp;len=strlen(str);for(j=len-1;i

3、j--){temp=str[i];str[i]=str[j];str[j]=temp;}}Sy7-3#includeintfun(intn){staticintp=1;p=p*n;returnp;}voidmain(){intn,i;intf=1;printf("inputmember:");scanf("%d",&n);for(i=1;i<=n;i++)f=fun(i);printf("%d!=%d",n,f);}Sy7-4#includeintsum(intx[],intn){inti,s
