15.字符串排序（15. string sorting） 79. (ReadDat) function to achieve read a English from the IN.DAT file into an array of strings in XX, please prepare the function SortCharD (), its function is: per character of the sequence of sorting, sorting the results according to the bank to re deposit the string array XX. The last call to writeDat (XX) the results output to a file in OUT2.DAT. Example: Original: dAe, BfC. CCbbAA Results: fedCBA. BbCCAA / * solution: Void sortchard (void) {int I, J, K; int str; Char temp; For (i=0; imaxline; i++) {str=strlen (xx[i]); For (j=0; jstr-1; j++) For (k=j+1; kstr; k++) If (xx[i][j]xx[i][k]) {temp=xx[i][j]; Xx[i][j]=xx[i][k]; Xx[i][k]=temp;}}} 80. (READDAT) function can read a English article from the file IN.DAT into the string array XX; (SORTCHARA), please prepare the function the function is: in units of characters according to the order from small to large, the results sorted according to the re stored in the string array XX, the last call (WRITEDAT) the results output to the XX OUT.DATK. Example: Original: dAe, BfC. CCbbAA Results:.ABCdef. AACCbb / * solution: Void sortcharA (void) {int I, J, K; int strl; Char temp; For (i=0; imaxline; i++) {str=strlen (xx[i]); For (j=0; jstr-1; j++) For (k=j+1; kstr; k++) If (xx[i][j]xx[i][k]) {temp=xx[i][j]; Xx[i][j]=xx[i][k]; Xx[i][k]=temp;}}} 81. function ReadDat () read 20 lines of data from in.dat file stored in the string array in XX (the string length is less than 80). Please prepare the function jsSort (), its function is: per string according to the given conditions of the sort, sort the results according to the bank to re deposit the string array XX, the last call to WriteDat (XX) the results output to a file in out.dat. Condition: from the middle part of the left One divides into two. string, according to the character of the ASCII value in descending order, the left part and the right part of the sorted exchange. If the original string length is odd, then the central character is not in c
