WRITE A C PROGRAM TO PERFORM BASIC STRING OPERATIONS

Program- #include #include int main() { char str1[20],str2[20],str3[20],str4[20]; printf(" Enter a string: "); scanf(" %s",str1); printf(" Enter second string: "); scanf("%s",str2);

printf(" Length of string 1=%d ",strlen(str1));

printf(" strcmp(str1,str2)=%d ",strcmp(str1,str2)); printf(" Reverse of string: %s ",strrev(str2)); printf("Enter third string: "); scanf("%s",str3); printf(" Enter fourth string: "); scanf("%s",str4); printf(" The concatenated string is %s ",strcat(str3,str4)); strcpy(str3,str4); printf(" Copied string is =%s ",str3); return 0;
