Explanation / Answer

If you have any doubts, please give me comment...

#include<stdio.h>

int main(){

char str[100];

printf("Enter a string: ");

scanf("%[^ ]s", str);

int i=0;

while(str[i]!=''){

if(str[i]>='A' && str[i]<='Z')

str[i] += 32;

else if(str[i]>='a' && str[i]<='z')

str[i] -= 32;

i++;

}

printf("result string: %s ", str);

return 0;

}

2)

#include<stdio.h>

#include<string.h>

int main(){

int i, j;

char inputStr[50][100], temp[100];

printf("Enter 10 words: ");

for(i=0; i<10; i++)

scanf("%s", inputStr[i]);

//using bubble sort

for(i=0; i<10; i++){

for(j = 0; j<10-i; j++){

if(strcmp(inputStr[j], inputStr[j+1])>0){

strcpy(temp, inputStr[j]);

strcpy(inputStr[j], inputStr[j+1]);

strcpy(inputStr[j+1], temp);

}

}

}

printf(" Lexicographical order: ");

for(i=0; i<10; i++){

printf("%s", inputStr[i]);

}

return 0;

}
